What is an example of a radius in math?
A radius is a line drawn from the centre of a circle to the edge of that circle. It is half the length of the diameter of the circle.
How many tangents can be drawn to a circle containing a point outside the circle?
Any tangent must contain a point outside the circle. So the answer to the question, as stated, is infinitely many. However, if the question was how many tangents to a circle can be drawn from a point outside the circle, the answer is two.
A compass draws all points that are equidistant from a fixed point thereby creating a locus of points for a circle?
A circle is the locus of all points equidistant from a given point, which is the center of the circle, and a circle can be drawn with a compass. (The phrase "locus of points for a circle" does not seem to be conventionally defined.) or true
How many circle can be drawn passing through two points?
There are infinite circles which can be drawn with 2 defined points.. Because if we have 2 points then we can draw infinite equal intersecting lines in infinite directions, These intersecting lines are the radii of the circles. Like : we have 2 points You can draw infinite isosceles triangles as taking the line joining the points For example (activity) : we have 2 points A, B so let's join A and B which will make line AB and so let's take another point C and place that point in such a way that AC = AB and we observe that there are infinite points which can be placed in such a way like how we marked C. Now draw a circle with center C and radius A, we will observe that the circle also cuts through B and so as we have infinite points like C, so we can have infinite circles ..... And so we conclude that infinite circles with different radii can be drawn through two defined distant points ...
What is the chord of a circle?
Take any circle and draw a straight line through it anywhere so that the line intersects the circle at two distinct points. The segment between the two points on the circle is the chord. A diameter, that is, a line segment through the center, could be a chord. But any shorter segment drawn through the circle and intersecting the circle at those two distinct points is a chord. It's just that simple. Need a link? You'll find one below.
Is the tangent of a circle is parallel to the radius drawn to the point of tangency?
Yes it is. Great work!
Is the tangent to a circle perpindicular to the radius drawn to the point of tangency?
Yes it is. Great work !
If a line is tangent to a circle what angle is formed if a radius is drawn to the point of tangency?
90 degrees. QED.
What is the measure of an arc intercepted by an angle formed by a tangent and a chord drawn from the point of tangency if the angle measures 40?
4/9*pi*r where r is the radius of the circle.
Point of intersection between a tangent and circle?
A line tyhat's tangent to a circle intersects the circle in exactly one single point. The radius drawn to that point is perpendicular to the tangent.
How many tangents can be drawn to a circle containing a point inside a circle?
No tangent No tangent
What is the measure of an arc intercepted by an angle formed by a tangent and a chord drawn from the point of tangency if the angle measures 40 degrees?
150
How do you find the length of a radius drawn from the center of the circle to a tangent?
It is the same length from the centre to any point on the circumference so just measure it
How many tangents can be drawn from a point on the circumference of a circle?
Only one which is a tangent to that circle.
Theorem Length of tangent drawn from external point to a circle are equal?
e
What is an example of a radius in math?
A radius is a line drawn from the centre of a circle to the edge of that circle. It is half the length of the diameter of the circle.
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a major arc whose measure is 230?
-- The major arc = 230 degrees-- The minor arc ... the arc between the tangents ... is (360 - 230) = 130 degrees.-- The line from the vertex of the angle to the center of the circle bisects the arc,so the angle between that line and the radius to each tangent is 65 degrees.-- The radius to each tangent is perpendicular to the tangent. So the radius, the tangent,and the line from the vertex to the center of the circle is a right triangle.-- In the right triangle, there's 90 degrees where the radius meets the tangent, and65 degrees at the center of the circle. That leaves 25 degrees for the angle at thevertex.-- With another 25 degrees for the right triangle formed by the other tangent,the total angle formed by the two tangents is 50 degrees.
