GCA - Geometry A Introduction to Transformations

Which transformation maps the pre-image, DEFG, to the image, D'E'F'G'?

RIGHT The transformation is a reflection.

Triangle ABC is transformed to create triangle MNL. Which statement is true?

RIGHT The transformation is rigid because corresponding side lengths and angles are congruent.

A transformation of rectangle ABCD results in rectangle A'B'C'D'. Which transformation maps the pre-image to the image?

RIGHT dilation

Which transformation maps quadrilateral EFGH to quadrilateral QRSP?

RIGHT rotation

Consider the two rectangles shown. A _______________ maps rectangle QRST to rectangle Q'R'S'T'.

RIGHT reflection

Triangle SRQ undergoes a rigid transformation that results in triangle VUT. Which statements are true regarding the transformation? Check all that apply.

RIGHT R corresponds to U. UV corresponds to RS.

Which description is true about the transformation shown?

RIGHT It is a dilation because the transformation is not isometric.

Triangle STV is transformed to create the image, triangle UTV. Which side in the image corresponds to TV in the pre-image?

RIGHT TV

Triangle XYZ is transformed to create triangle X'Y'Z'. The side lengths of both triangles are shown. XY = 10 cm X'Y'= 10 cm YZ = 9 cm Y'Z'= 9 cm ZX = 4 cm Z'X'= 4 cm Is this a rigid transformation? Explain.

RIGHT Yes, the pre-image and image have the same side length measures.

A transformation of ΔSTV results in ΔUTV. Which transformation maps the pre-image to the image?

RIGHT reflection
