The smallest angle of rotation that maps an image to itself is 45°.

Front

What is the result of rotating point A(3, -5) 90° counterclockwise about the origin?

Back

The coordinates of A' after rotation are (-5, 3).

Front

What is the smallest angle of rotation that maps a regular pentagon to itself?

Back

The smallest angle of rotation that maps a regular pentagon to itself is 72°.

Front

Write the translation rule for moving a point 2 units right and 1 unit down.

Back

The translation rule is (x + 2, y - 1).

Front

Are two figures congruent if one is a dilation of the other?

Back

No, the figures are NOT Congruent (dilation).

Front

What is a transformation that preserves the shape and size of a figure?

Back

A congruence transformation preserves the shape and size of a figure.

Front

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

Back

The effect of a 180° rotation on a point (x, y) is to map it to (-x, -y).

Front

What type of transformation is a slide of a figure in a straight line?

Back

A slide of a figure in a straight line is called a translation.

Front

What is the result of a dilation with a scale factor of 2 on a triangle with vertices at (1, 1), (2, 2), (3, 3)?

Back

The new vertices after dilation will be (2, 2), (4, 4), (6, 6).

Front

What is the definition of congruent figures?

Back

Congruent figures are figures that have the same shape and size.
