question

This graph shows a triangle.

Which graph shows a rotation of the triangle?

key idea

In a reflection across a line, every point in a figure moves to a point directly on the opposite side of the line. The new point and the original point are the same distance from the line.

In a

rotation,

every point in a figure moves the same angle and direction around a fixed point (or center of rotation).

In a

translation,

every point in a figure moves the same distance and direction.

solution

red X symbol, This graph shows a translation of the triangle. Every point on the triangle moves right 2 units.

red X symbol, This graph shows a reflection of the triangle across a vertical line.

green checkmark, This graph shows a counterclockwise rotation of the triangle.
