Angles Inside and Outside Circles

Front

What is the measure of an angle formed by two tangents drawn from a point outside a circle?

Back

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

Define the term 'arc' in the context of a circle.

Back

An arc is a portion of the circumference of a circle.

Front

What is the formula to find the measure of an angle inside a circle formed by two chords?

Back

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

Front

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

Back

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

Front

If angle BDC measures 40°, what is the relationship between angle BDC and the intercepted arcs?

Back

Angle BDC is formed by two chords and is equal to half the sum of the measures of the intercepted arcs.

What is the formula to find the measure of an angle formed by two secants intersecting outside a circle?

Back

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

Front

How do you calculate the measure of an arc given the angle formed by two tangents?

Back

The measure of the arc is equal to twice the measure of the angle formed by the tangents.
