Vocab flashcard on Transformations

Front

Transformation:

Back

Altering an image in a plane based on a given operation.

Front

Translation: Sliding a figure on a coordinate plane, maintaining congruency and orientation.

Back

Sliding a figure on a coordinate plane, maintaining congruency and orientation.

Front

What is a reflection?

Back

Flipping a figure over a line; maintains congruency but not orientation, like a mirror.

Front

Rotation: rotating a figure a certain degree around a point, maintains congruency.

Back

we rotate a figure a certain degree around a point, maintains congruency

Front

Dilation: enlarging/reducing a figure, does NOT maintain congruency; figures are SIMILAR.

Back

Enlarging/reducing a figure, does NOT maintain congruency; figures are SIMILAR.

Front

Congruent figures:

Back

Same size and shape.

Front

Two figures are similar if they have the same angle measures and proportional corresponding sides.

Back

Same angle measures, corresponding sides are proportional

Front

Two angles are supplemental if their measures add up to 180 degrees.

Back

180 degrees

Front

Two angles are complementary if their measures add to 90°.

Back

Their measures add to equal 90 degrees.

Front

Corresponding angles in parallel lines and transversals are...

Back

congruent
