Question

Trapezoid JKLM has points J(-2,-4), K(2,-4), L(4,2), and M(-4,2) which transformation will map the trapezoid to itself?

Reflection across the x-axis

Reflection across the y-axis

Rotation of 90 degrees about the origin

Rotation of 180 degrees about the origin

Answer 1

(B)

Explanation:

JKLM is a trapezoid with points J(-2,-4), K(2,-4), L(4,2), and M(-4,2) plotted on XY-Plane.

By mapping, we mean that that the figure obtained after the translation is same as the original one.

The transformation which will map the trapezoid itself will be the reflection across y-axis.

Hence, option (B) is correct.
