How many tangents can be drawn from a single point?
Two tangents can be drawn from a point outside a circle to the circle. The answer for other curves depends on the curve.
What is the longest chord that can be drawn on a circle?
The diameter (across the widest part) is the longest chord that can be drawn on a 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.
What is the cord of a circle?
A cord of a circle is any line segment connecting any two unique points on the curve. Any cord drawn through the center of the circle will be a diameter of the circle. These cords will be the longest cords that can be drawn, and any one of them can bisect the circle into two identical parts.
What is A line segment drawn through the center of the circle with endpoint on the circle?
A line segment drawn through the centre of a circle and having endpoints on the circumference of that circle is called the diameter. Notably, a line segement with one endpoint at the centre of the circle and one anywhere on the circumference of the circle is called the radius, and is exactly half the length of the diameter.
How many tangents can be drawn to a circle containing a point inside a circle?
No tangent No tangent
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.
How many tangents can be drawn from a single point?
Two tangents can be drawn from a point outside a circle to the circle. The answer for other curves depends on the curve.
How many parallel tangents can be drawn to a circle?
An infinite amount
Number of tangents drawn from an external point to a circle?
2
How many tangents can be drawn from a point on the circumference of a circle?
Only one which is a tangent to that circle.
How many tangents can be drawn to a point on a circle?
Always one for sure, and never more than one.
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 200 degrees?
The angle between the two tangents is 20 degrees.
How many tangents can be drawn on three circles if they dont lie within each other?
if you mean common tangents there can be only 2 tangents
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a minor arc whose measure is 80 degrees?
100 degrees
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 243 and the minor arc measures 117?
63o. Join the points where the tangents touch the circle to its centre to form a quadrilateral (two meeting tangents and two radii). These angles are both 90o, summing to 180o. Thus the other two angles - the one at the centre of the circle and the one where the tangents meet - sum to 360o - 180o = 180o (they are supplementary). The centre angle is given as 117o (the minor arc), so the angle where the tangents met is 180o - 117o = 63o.
Why do the tangents drawn at the ends of a chord of a circle make equal angles with the chord?
Because in effect an isosceles triangle has been constructed and the base angles are always equal.
