What are tangents to a circle from a point called?
Often circles lines points et cetera are named.In this answer I call the circle C, the Tangent T, the point P, the center of the circle OThey are called just what your question asked:"The tangent to circle C through point P is T"P may not be inside C but may be on CIf P is outside C there are twotangents T1 and T2If P is on C there is one tangent TT is perpendicular to the radius at the point of tangency
Can Two intersecting lines both be tangents?
It's possible for any number of intersecting lines to all be tangent to the same circle. Think of a dinner plate sitting in a pizza box that just exactly fits it. Looking straight down from above, it looks like a circle inside a square. All four sides of the square are tangent to the circle.
What is the inside measurement of a circle called?
The inside measurement of a circle is called the diameter. It is the distance across the circle, passing through the center.
What is the radius equation inside the circle x squared plus y squared -8x plus 4y equals 30 that meets the tangent line y equals x plus 4 on the Cartesian plane showing work?
Circle equation: x^2 +y^2 -8x +4y = 30 Tangent line equation: y = x+4 Centre of circle: (4, -2) Slope of radius: -1 Radius equation: y--2 = -1(x-4) => y = -x+2 Note that this proves that tangent of a circle is always at right angles to its radius
Where can you find a definition and picture of a concentric hexagon?
"Having the same center" is the meaning of concentric. A regular hexagon in a concentric circle can be viewed by using the link and looking at the "active construction" window where there is a short animation of the construction of a hexagon inside a circle. It is posted by our friends at Wikipedia, where knowledge is free.
How many tangents can be drawn to a circle containing a point inside a circle?
No tangent No tangent
How many tangents can be drawen to a circle contaning a point inside the circle?
None. A tangent is a line that has exactly onepoint in common with the circle.If it contained a point inside the circle, then it would have to pass through twopoints on the circle.
A circle inside a polygon where each side of the polygon is tangent to the circle?
the circle is inscribed in the polygon
A line that is tangent to two circles?
... touches each circle in exactly one point on each circle. given any two circles where none is entirely inside or inside and tangent to the other, there are at most four straight lines that are tangent to both circles.
If the measure of a tangent chord angle is 74 then what is the measure of the intercepted arc inside the angle?
Through construction I make it to 148° of the circle or 2,583 radians 90 - 74 = 16 180 - (2*16) = 148 148/180 * pi = 2,583
Does a trigonometry tangent relate to a circle's tangent?
A circle's tangent is exactly the same as a triangle's tangent. If you look at a circle, you can make the radius the hypotenuse. Then make a vertical line from the point, and a horizontal line from the center. If you look, you have a triangle made inside the circle. This is why angles can be measured in radians, a unit that is derived from the circumference of a circle.-------------------------------------------------------------------------------------------By doing a little calculus, we find that the slope of the equation of a circle-the slope of the tangent line-is given by the tangent of an angle.AnswerEverything written above is correct, but doesn't have anything to do with tangents (in the circle sense of the word). Suppose you're given an angle theta. Draw a circle together with two radii, one horizontal and the other at an angle theta from the first one. (So far, this is the same as above.) Now draw the tangent to the circle at X, the point where the non-horizontal radius meets the circumference. Let Y be the point where this tangent meets the horizontal line through the centre. Then, assuming the radius is 1, tan(theta) is the distance XY, which is the length of part of the tangent.

How many tangents can be drawn to a circle containing a point inside the circle?
None can. A tangent is a line that touches a circle at only one point. If it wentthrough a point inside the circle, then it would have to touch the circle at twopoints ... one on the way in and another one on the way out.
How do you draw a tangent to a circle from a point on its circumference?
Short instructions:Construct the diameter of the circle at the tangent point Construct a line at right angles to the diameter at the tangent point. this is a tangent to the circle at that point.Detailed instructions with compass and straight edge:Given: circle C with a point T on the circumference Sought: Tangent to C at TFind the center circle CPlace the needle of the compass on the (circumference of) circle C (anywhere), draw a circle [circle 1] (I think circle 1 has to be smaller than twice the diameter of circle C).Without changing the compass size, place the needle of the compass on the intersection of circles C and circle 1, draw a circle (circle 2)Without changing the compass size, place the needle of the compass on the other intersection of circles C and circle 1, draw a circle (circle 3)Connect the intersections of circle 1 and circle 2 (one is outside and one inside circle A) this we call [ line 1]Connect the intersections of circle 2 and circle 3 (also here one is outside and one inside C) [line 2]The intersection of line 1 and Line 2 is [O]. This is the center of circle CDraw a line [line 3] from [O] through [T] and beyondConstruct the diameter of the circle at [T] (the point for the tangent) and extend it beyond the circumference of circle C With your compass needle at [T] mark off equal distances on [line 3] inside and outside circle C. We call these points [4] & [5]Increase the compass size somewhat and with the needle at [4] draw a circle [circle 4]Without changing the compass draw [circle 5] centered on [5]Construct a line perpendicular to line 3 at [T]The line through the intersections of circle 4 and circle 5 is the sought tangent at [T]Note: although the instructions say "draw a circle" often it is sufficient to just mark a short arc of the circle at the appropriate place. This will keep the drawing cleaner and easier to interpret.
Find the equations of the lines that are tangent to the ellipse x squared plus y squared equals sixteen and that also pass through the point x equals 4 and y equals 6?
This is not possible, since the point (4,6) lies inside the circle : X2 + Y2 = 16 Tangents to a circle or ellipse never pass through the circle

Is it true or false that the measure of a tangent-chord angle is twice the measure of the intercepted arc inside the angle?
It is true that the measure of a tangent-chord angle is half the measure of the intercepted arc inside the angle. When a tangent line intersects a chord of a circle, it creates an angle between the tangent line and the chord, known as the tangent-chord angle. If we draw a segment from the center of the circle to the midpoint of the chord, it will bisect the chord, and the tangent-chord angle will be formed by two smaller angles, one at each end of this segment. Now, the intercepted arc inside the tangent-chord angle is the arc that lies between the endpoints of the chord and is inside the angle. The measure of this arc is half the measure of the central angle that subtends the same arc, which is equal to the measure of the angle formed by the two smaller angles at the ends of the segment that bisects the chord. Therefore, we can conclude that the measure of a tangent-chord angle is half the measure of the intercepted arc inside the angle.
