IM Geometry Unit 2

Front

What is a rectangle?

Back

A rectangle is a quadrilateral with four right angles and opposite sides that are equal in length.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size, meaning all corresponding sides and angles are equal.

Front

What is the definition of corresponding parts in geometry?

Back

Corresponding parts are the sides or angles that are in the same relative position in two congruent figures.

Front

What is the Side-Angle-Side (SAS) Triangle Congruence Theorem?

Back

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

Front

What is the Angle-Side-Angle (ASA) Triangle Congruence Theorem?

Back

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

Front

What is the Side-Side-Side (SSS) Triangle Congruence Theorem?

Back

The SSS theorem states that if all three sides of one triangle are congruent to all three sides of another triangle, then the two triangles are congruent.

Front

What is the definition of rigid motion?

Back

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

Front

What is a reflection in geometry?

Back

A reflection is a type of rigid motion where a figure is flipped over a line, creating a mirror image.

Front

What is a translation in geometry?

Back

A translation is a type of rigid motion that slides a figure from one position to another without changing its shape or orientation.

Front

What is a rotation in geometry?

Back

A rotation is a type of rigid motion that turns a figure around a fixed point at a certain angle.
