Geometry Benchmark Review

Front

What is the relationship between corresponding angles when two parallel lines are cut by a transversal?

Back

Corresponding angles are equal.

Front

If two angles are alternate exterior angles, what can be said about their measures when the lines are parallel?

Back

Alternate exterior angles are equal.

Front

What does SSS stand for in triangle congruence?

Back

SSS stands for Side-Side-Side, meaning if three sides of one triangle are equal to three sides of another triangle, the triangles are congruent.

Front

What is a rigid motion in geometry?

Back

A rigid motion is a transformation that preserves distance and angle measures, such as reflection, rotation, and translation.

Front

What is the definition of dilation in geometry?

Back

Dilation is a transformation that alters the size of a figure but not its shape.

Front

How do you classify a triangle with one angle greater than 90 degrees?

Back

It is classified as an obtuse triangle.

Front

What is the definition of an isosceles triangle?

Back

An isosceles triangle has at least two sides that are equal in length.

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

If two triangles have two sides and the included angle equal, what postulate can be used to prove they are congruent?

Back

The SAS (Side-Angle-Side) postulate.

Front

What is the definition of an acute triangle?

Back

An acute triangle is a triangle where all three angles are less than 90 degrees.
