ACTVITY ON ANGLES FORMED BY TANGENTS AND SECANTS

If two secants intersect in the exterior of the circle, then the angle formed is one - half the positive difference of the measures of the intercepted arcs.

• TRUE

• FALSE

If two tangents intersect in the exterior of the circle, then the angle formed is one - half the sums of the measures of the intercepted arcs.

• TRUE

• FALSE

If a secant and a tangent intersect at a point of tangency, then the measure of each angle is one half the measure of the intercepted arc.

• TRUE

• FALSE

If a tangent and a secant segment are drawn to a circle from the same exterior point , then the square of the length of the tangent segment is equal to the quotient of the lengths of the secant segment and its external secant segment.

• TRUE

• FALSE

If a line is perpendicular to the radius at the point on a circle, then the line is secant to the circle.

• TRUE

• FALSE

If measure of arc DF = 79 and measure of arc HG is 163, find measure of angle HEG.

if measure of line segment AD = 4 and measure of line segment DC = 12, find measure of line segment AB .

JK and KL are tangents intersect in the exterior of circle O. If KL = 24, find JK.
