Front

Define 'Interior Angle' in the context of a circle.

Back

An interior angle is formed by two chords in a circle that meet at a point inside the circle.

Front

What is the formula to find the measure of an angle formed by two intersecting chords?

Front

If arc AB measures 100° and arc CD measures 80°, what is the measure of the angle formed by these arcs?

Back

(1/2)(100° + 80°) = 90°

Front

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

Back

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

Front

How do you calculate the measure of an angle formed by two tangents that intersect outside a circle?

Back

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