Rigid Transformations, Angles, and Congruence

Front

What does a translation do to an image?

Back

A translation slides the image to a different position without changing its shape or orientation.

Front

If angle P measures 60 degrees, what is the measure of angle Q if they are supplementary?

Back

Angle Q measures 120 degrees.

Front

What is the value of angle A if it is given that angle A is 98 degrees?

Back

∠A = 98°.

Front

Figures that are the same size, same shape, and same angles are called what?

Back

Congruent.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What does a rotation do to an image?

Back

A rotation turns the image around a fixed point at a certain angle.

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

What is the definition of congruence in geometry?

Back

Congruence means that two figures have the same shape and size.

Front

What is the difference between a translation and a reflection?

Back

A translation slides a figure without changing its orientation, while a reflection flips it over a line.

Front

If two angles are complementary, what is the relationship between their measures?

Back

The sum of their measures is 90 degrees.
