Geometry 1.06: Transformations 1

What is true about every rotation?

The angles in the image and pre-image are congruent.

Which translation vectors could have been used for the pair of figures? Select each correct answer. Two congruent figures that look like thick arrows but are pointing downwards. One figure is slight above and to the right of the other figure.

Susan will rotate triangle ABC 180° about one of the labeled points. Susan says, "The image will not touch the pre-image at all." Which points could be her center of rotation? Select each correct answer. triangle a b c with point d inside the triangle. point e and f are outside the triangle. point e is approximately half an inch below segment b c. point f is approximately 4 inches to the right of side a c. triangle a b c is approximatley 3 inches long at its longest side.

What kind of transformation is illustrated in this figure? Two obtuse scalene triangles with the pre image labeled A B C and the image labeled A prime, B prime, C prime. Each point of the pre image and image are equidistant from an invisible line and look like flipped mirror images.

reflection

Which figures demonstrate a translation? Select each correct answer.

two 5-sided polygon that are the same shape, size, and orientation. One is at the top left corner and the other one is at the bottom right corner. two 5-sided polygon that are the same in size, shape, and orientation. they sit side by side but overlap a little.
