Front

What is a dilation in geometry?

Back

A transformation that changes the size of a figure but not its shape, characterized by a scale factor.

Front

What is the sequence of transformations that maps figure 1 onto figure 2 and then figure 2 onto figure 3 if they are congruent?

Back

A translation followed by a rotation.

Front

How do you reflect a point A(x, y) using the rule (x, y) -> (-x, y)?

Back

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

Front

What is the result of dilating point B(4, 4) by a scale factor of 3?

Back

B' (12, 12).

Front

What is the translation rule for moving a point (x, y) to (x - 1, y - 3)?

Back

This rule shifts the point left by 1 unit and down by 3 units.

Front

What is the result of reflecting point C(-6, 2) using the rule (x, y) -> (x, -y)?

Back

C'(-6, -2).

Front

What is the definition of a rigid motion in geometry?

Back

A transformation that preserves distance and angle measures, including translations, rotations, and reflections.

Front

What is the effect of a rotation on a figure?

Back

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

Front

What is the difference between a translation and a reflection?

Back

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

Front

If triangle ABC is translated by the rule (x, y) -> (x + 2, y + 3), what happens to the coordinates of point A(1, 1)?

Back

Point A will move to A'(3, 4).
