Lesson 30 A/B - Chords, Arcs and Inscribed Angles

Front

What do congruent arcs in a circle imply?

Back

Congruent arcs have congruent chords.

Front

What is the measure of x if x = 2?

Back

x = 2

Front

If a = 93° and b = 74°, what are the values of a and b?

Back

a = 93°, b = 74°

Front

What is the value of x if x = 13°?

Back

x = 13°

Front

Find x if x = 10.

Back

x = 10

Front

What is the relationship between the measure of an inscribed angle and the arc it intercepts?

Back

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

Front

Define a chord in a circle.

Back

A chord is a line segment with both endpoints on the circle.

Front

What is an arc in a circle?

Back

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

Front

How do you find the length of a chord given the radius and the angle subtended at the center?

Back

Use the formula: Length of chord = 2 * r * sin(θ/2), where r is the radius and θ is the angle in radians.

Front

What is the measure of a central angle in relation to its intercepted arc?

Back

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