Fall Test Transformations Flashcard 8th

Front

What does it mean for two shapes to be similar?

Back

Two shapes are similar if they have the same shape but may differ in size. Their corresponding angles are equal, and their corresponding sides are in proportion.

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a shape over a line, creating a mirror image of the original shape.

Front

What is a rotation in geometry?

Back

A rotation is a transformation that turns a shape around a fixed point, known as the center of rotation, by a certain angle.

Front

What is a translation in geometry?

Back

A translation is a transformation that slides a shape from one position to another without changing its size, shape, or orientation.

Front

What is the difference between rotation and reflection?

Back

Rotation turns a shape around a point, while reflection flips a shape over a line.

Front

What does it mean to map one shape onto another?

Back

To map one shape onto another means to apply transformations (like translation, rotation, or reflection) so that the first shape coincides with the second shape.

Front

What is the effect of a 90-degree clockwise rotation on a point (x, y)?

Back

The new coordinates after a 90-degree clockwise rotation are (y, -x).

Front

What is the effect of a 90-degree counterclockwise rotation on a point (x, y)?

Back

The new coordinates after a 90-degree counterclockwise rotation are (-y, x).

Front

What is the transformation sequence for mapping triangle UVW to U'V'W' if it involves rotation and reflection?

Back

The transformation sequence is rotation followed by reflection.

Front

How do you determine if two shapes are congruent?

Back

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