What is the measure of arc JL?

Back

Arc JL measures 78 degrees.

Front

If angle a is 93 degrees and angle b is 74 degrees, what can you say about their relationship?

Back

Angles a and b are complementary if they add up to 180 degrees.

Front

What is the length of tangent AC to a circle if AC and BC are both tangent?

Back

The length of tangent AC is 21.

Front

Define a tangent line in relation to a circle.

Back

A tangent line is a straight line that touches the circle at exactly one point.

Front

What is the relationship between the angles formed by two tangents from a point outside the circle?

Back

The angles formed by two tangents from a point outside the circle are equal.

Front

How do you calculate the measure of an arc in a circle?

Back

The measure of an arc can be calculated using the central angle that subtends the arc.

Front

What is the formula for finding the length of an arc?

Back

The length of an arc can be calculated using the formula: Length = (θ/360) * 2πr, where θ is the central angle in degrees and r is the radius.

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 degrees.
