Unit 3 - Semester Exam Review

Front

What is the sequence of transformations that maps a figure onto itself?

Back

Reflect over the y then reflect over the x.

Front

What series of transformations maps triangle ABC onto triangle DEF?

Back

Reflect over x then translate left 6 up 1.

Front

Identify the transformation: ABC → A'B'C'.

Back

The transformation is a 90° rotation.

Front

How many degrees should a parallelogram be rotated to carry it onto itself?

Back

180 degrees.

Front

What is the result of the translation (x, y) → (x - 6, y + 2) applied to point (3, 4)?

Back

The new coordinates are (-3, 6).

Front

Define reflection in geometry.

Back

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

Front

What is a rotation in geometry?

Back

A transformation that turns a figure around a fixed point by a certain angle.

Front

Explain translation in geometry.

Back

A transformation that moves every point of a figure the same distance in the same direction.

Front

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

Back

The new coordinates will be (y, -x).

Front

What is the effect of a 180° rotation on point (x, y)?

Back

The new coordinates will be (-x, -y).
