Question

do questions 1 - 5 on scantron. for questions 6 - 10, write answers on qu. question 3 select all the points that stay in the same location after being reflected across line l, shown here a.point a b. point b c.point c d.point d e.point e question 4 here are four original triangles that have each been transformed by a different transformation. which transformation is not a rigid transformation

Explanation:

Step1: Recall reflection property

A point on the line of reflection remains in the same location after reflection. Points C and E lie on line $\ell$, so they will not change position.

Step2: Analyze other points

Points A, B and D are not on line $\ell$. They will move to new positions after reflection across line $\ell$.

Step1: Define rigid - transformation

A rigid transformation preserves distance and angle measures. Translations, rotations and reflections are rigid transformations. Dilation is a non - rigid transformation.

Step2: Analyze each option

Option A looks like a dilation as the size of the triangle has changed. Options B, C and D look like translations, rotations or reflections which are rigid transformations.

Answer:

C. Point C, E. Point E
