Flashcard on Arcs, Inscribed and Central Angles

Front

What is the measure of an inscribed angle in relation to the intercepted arc?

Back

The measure of an inscribed angle equals half the measure of the intercepted arc.

Front

If the measure of arc ABC is 210°, what is the measure of angle AOC?

Back

150°

Front

What is the relationship between central angles and intercepted arcs?

Back

The measure of a central angle is equal to the measure of the intercepted arc.

Front

How do you find the measure of an inscribed angle?

Back

The measure of an inscribed angle is half the measure of the intercepted arc.

Front

What is the sum of the measures of angles in a triangle?

Back

The sum of the measures of angles in a triangle is always 180°.

Front

If angle AOC is 150°, what is the measure of arc ABC?

Back

The measure of arc ABC is also 150°.

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 half the sum of the measures of the intercepted arcs.

Front

What is the measure of an angle formed by two secants that intersect outside a circle?

Back

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

Front

If angle A is 45°, what is the measure of the intercepted arc?

Back

The measure of the intercepted arc is 90°.

Front

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

Back

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