C3M9 Test Review

Determine if the following statement is true or false.

"The quadrilaterals are congruent."

The quadrilaterals are congruent, describe the sequence of transformations that maps quadrilateral ABCD onto quadrilateral JKLM.

• The quadrilateral was translated 5 units right and 4 units down

• The quadrilateral was dilated with a scale factor of 2

Triangle ABC is congruent to △PQR. Which of the following sequences of transformations maps △ABC onto △PQR?

• translation 2 units left, translation 3 units up

• reflection across y-axis, translation 3 units up

• reflection across x-axis, translation 3 units up

• rotation 90° clockwise about the origin, translation 3 units up

Which figures are congruent based on a 90° clockwise rotation about the origin?

• △ABC≅△QRS

• △ABC≅△VUT

• △HJK≅△QRS

• □LMNP≅□DEFG

Describe a congruence transformation that maps triangle ABC onto triangle EFG.

• Reflection across the y-axis then translation 7 left and 3 down

• Dilation with a scale factor of 0.5
