Angles formed by chords, secants and tangents

Front

What is the measure of an angle formed by two chords that intersect inside a circle?

Back

The measure of the angle is equal to the average of the measures of the arcs intercepted by the angle and its vertical angle.

Front

How do you find the measure of an angle formed by a tangent and a chord?

Back

The measure of the angle formed by a tangent and a chord through the point of contact is equal to half the measure of the intercepted arc.

Front

What is the relationship between the angles formed by two secants that intersect outside a circle?

Back

The measure of the angle formed by two secants is equal to half the difference of the measures of the intercepted arcs.

Front

If two chords intersect inside a circle, how do you calculate the angle formed?

Back

The angle formed is equal to half the sum of the measures of the arcs intercepted by the angle.

Front

What is the formula for finding the angle formed by two tangents drawn from a point outside a circle?

Back

The angle formed is equal to half the difference of the measures of the intercepted arcs.

Front

How do you determine the measure of an angle formed by a secant and a tangent?

Back

The measure of the angle is equal to half the measure of the intercepted arc.

Front

What is the measure of an angle formed by two intersecting chords in a circle?

Back

The measure of the angle is equal to the product of the lengths of the segments of each chord.

Front

What is the significance of the intercepted arcs in calculating angles formed by chords, secants, and tangents?

Back

Intercepted arcs are crucial as they directly influence the measures of the angles formed by chords, secants, and tangents.
