Front

What is an angle bisector?

Back

An angle bisector is a line or ray that divides an angle into two equal parts.

Front

What is the measure of an arc intercepted by an angle?

Back

The measure of an arc intercepted by an angle is equal to the measure of the angle in degrees.

Front

How do you determine the value of x in a geometric diagram?

Back

To determine the value of x, use the properties of angles, triangles, or other geometric relationships present in the diagram.

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

If m∠MN = 87°, what can be inferred about ∠MON?

Back

If m∠MN = 87°, then ∠MON can be equal to 87° if they are corresponding angles or if they are part of a linear pair.

Front

What is a perpendicular bisector?

Back

A perpendicular bisector is a line that divides a segment into two equal parts at a 90-degree angle.

Front

What is the definition of a midpoint?

Back

A midpoint is the point that divides a segment into two equal lengths.

Front

What is the relationship between angles and arcs in a circle?

Back

The measure of an angle formed by two chords is equal to half the measure of the intercepted arc.

Front

What are the properties of a triangle?

Back

A triangle has three sides, the sum of the interior angles is always 180 degrees, and it can be classified as scalene, isosceles, or equilateral.

Front

What is the formula for the sum of interior angles in a polygon?

Back

The sum of the interior angles of a polygon with n sides is (n-2) × 180 degrees.
