Kendall Hunt Geometry Unit 2 Review

Front

What is a rigid motion in geometry?

Back

A rigid motion is a transformation that preserves distance and angle measures, meaning the shape and size of the figure remain unchanged.

Front

What does it mean for triangles to be congruent?

Back

Triangles are congruent if they have the same size and shape, which can be proven using congruence theorems.

Front

What is the Angle-Side-Angle (ASA) congruence theorem?

Back

The ASA theorem states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the definition of an isosceles triangle?

Back

An isosceles triangle is a triangle that has at least two sides of equal length and the angles opposite those sides are equal.

Front

How do you find the measure of an unknown angle in a triangle?

Back

To find an unknown angle in a triangle, use the fact that the sum of the interior angles in a triangle is always 180 degrees.

Front

What is the definition of 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 Side-Angle-Side (SAS) congruence theorem?

Back

The SAS theorem states that if two sides and the included angle of one triangle are equal to two sides and the included angle of another triangle, then the triangles are congruent.

Front

What is the purpose of reflecting a shape in geometry?

Back

Reflecting a shape creates a mirror image of the shape across a line, preserving its size and shape.

Front

What is the definition of translation in geometry?

Back

Translation is a transformation that moves every point of a shape the same distance in the same direction.

Front

What is the relationship between angles formed by parallel lines and a transversal?

Back

When a transversal crosses parallel lines, it creates corresponding angles that are equal and alternate interior angles that are also equal.
