Front

What is a radius of a circle?

Back

A radius is a line segment from the center of the circle to any point on its circumference.

Front

What is a diameter of a circle?

Back

A diameter is a line segment that passes through the center of the circle and has its endpoints on the circle. It is twice the length of the radius.

Front

If ray OR is the angle bisector of ∠POQ, what does that mean?

Back

It means that ray OR divides the angle ∠POQ into two equal angles.

Front

What is the relationship between the measures of angles formed by an angle bisector?

Back

The measures of the angles formed by an angle bisector are equal.

Front

What is the Triangle Inequality Theorem?

Back

The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

Can the side lengths 3, 5, and 8 form a triangle?

Back

No, because 3 + 5 is not greater than 8.

Front

What are vertical angles?

Back

Vertical angles are the angles opposite each other when two lines intersect. They are always congruent (equal in measure).

Front

What is the measure of a right angle?

Back

A right angle measures 90 degrees.

Front

What is the sum of the interior angles of a triangle?

Back

The sum of the interior angles of a triangle is always 180 degrees.

Front

What is an acute angle?

Back

An acute angle is an angle that measures less than 90 degrees.
