Congruence and Angle Relationships

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 one can be transformed into the other through rigid motions such as translation, rotation, or reflection.

Front

What is a rigid motion?

Back

A rigid motion is a transformation that preserves the shape and size of a figure, including translations, rotations, and reflections.

Front

What is translation in geometry?

Back

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 rotation in geometry?

Back

Rotation is a type of rigid motion that turns a figure around a fixed point, called the center of rotation, by a certain angle.

Front

What is reflection in geometry?

Back

Reflection is a type of rigid motion that flips a figure over a line, creating a mirror image of the original figure.

Front

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

Back

The sum of the measures of two complementary angles is 90 degrees.

Front

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

Back

The sum of the measures of two supplementary angles is 180 degrees.

Front

What is the measure of Angle 2 if it is given as 55 degrees?

Back

Angle 2 measures 55 degrees.

Front

What is the measure of Angle 5 if it is given as 125 degrees?

Back

Angle 5 measures 125 degrees.

Front

What is the measure of Angle 8 if it is given as 55 degrees?

Back

Angle 8 measures 55 degrees.
