Grade 8 gradeMath subjectFree quiz

Grade 8 transformations move figures on the coordinate plane: translations, reflections, rotations, and dilations. Rigid motions preserve distance and angle, so they produce congruent images; dilations change size and produce similar images. Students also compose two moves and name the single transformation that matches the result.

What you practice

These are the Grade 8 Transformations & Congruence skills this quiz is built around.

Find the image of a point after a translation, reflection, or rotation about the origin.
Apply a dilation from the origin and state the scale factor from corresponding lengths.
Tell whether a sequence of transformations shows congruence, similarity, or neither.

A useful tip

Reflection over the x-axis changes the sign of y, not x. Mixing the axes is a common mapping error when students memorize rules without a sketch.
