8th math: Transformations QUEST

Front

What happens to the y-coordinate when reflecting a point across the y-axis?

Back

The y-coordinate stays the same.

Front

What is the rule for translating a point left 1 and down 3?

Back

Translate left 1, down 3.

Front

What are the coordinates of point K' after rotating ΔJKL 180º clockwise if K is at (2, 3)?

Back

K' (2, -3)

Front

Does the figure have rotational symmetry if it looks the same after a rotation of 180º?

Back

No, it does not have rotational symmetry.

Front

What type of figures are the pre-image and image in a transformation?

Back

Congruent figures.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape to create a new shape.

Front

What is the effect of a reflection across the x-axis on the coordinates of a point?

Back

The x-coordinate stays the same, and the y-coordinate changes sign.

Front

What does it mean for two figures to be congruent?

Back

Two figures are congruent if they have the same shape and size.

Front

What is the rule for reflecting a point across the y-axis?

Back

Change the sign of the x-coordinate.

Front

What is the result of rotating a point (x, y) 90º clockwise?

Back

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