Front

Translate the point A (-3, 4) right 5 and up 1. What is the new coordinate?

Back

(2, 5)

Front

If you rotate point A (-3, 4) 180° about the origin, what is the new coordinate A'?

Back

(-3, -4)

Front

What does it mean for T to be the midpoint of segment BG?

Back

T divides segment BG into two equal parts.

Front

What is the ordered pair rule for transforming point A(-9, 2) to A'(-2, 9)?

Back

Front

How do you translate triangle ABC to triangle A'B'C'?

Back

left two, up 9.

Front

What is the definition of a translation in geometry?

Back

A translation moves every point of a shape the same distance in the same direction.

Front

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

Back

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

Front

What does it mean for two angles to be congruent?

Back

Two angles are congruent if they have the same measure.

Front

What is the formula for finding the midpoint of a segment with endpoints (x1, y1) and (x2, y2)?

Back

Front

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