Perpendicular and Angle Bisectors Practice

Front

What is a perpendicular bisector?

Back

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

Front

What is an angle bisector?

Back

A ray that divides an angle into two equal angles.

Front

In congruent triangles, what can be said about corresponding sides?

Back

They are equal in length.

Front

If two angles are complementary, what is the sum of their measures?

Back

90 degrees.

Front

If two angles are supplementary, what is the sum of their measures?

Back

180 degrees.

Front

What is the relationship between the angles formed by perpendicular lines?

Back

They form four right angles (90 degrees each).

Front

How do you find the length of a missing side in a right triangle?

Back

Use the Pythagorean theorem: a² + b² = c².

Front

What is the measure of each angle in an equilateral triangle?

Back

Each angle measures 60 degrees.

Front

What is the definition of congruent triangles?

Back

Triangles that are identical in shape and size, with corresponding sides and angles equal.

Front

If the measure of angle XWY is 20 degrees and angle XWZ is 40 degrees, what can be inferred about angles XYW and YZW?

Back

Angle XYW is equal to angle YZW because they are vertical angles.
