Green Bridge Learning Resource For Transformations On The Cartesian Plane

Overview

A transformation moves or resizes a shape on the Cartesian plane. The four you need are translations (slides), reflections (flips), rotations (turns) and enlargements (dilations, which resize). Each is described fully by a small amount of precise information.

In this lesson you will describe and perform translations, reflections, rotations and enlargements, learning exactly what details are needed to specify each one completely so that it can be reproduced.

A slide by a column vector is a: A. reflection B. rotation C. translation D. enlargement Answer: C
Reflecting (3, 2) in the y-axis gives: A. (3, -2) B. (-3, 2) C. (-3, -2) D. (2, 3) Answer: B
To describe a rotation fully you must give: A. only the angle B. center, angle and direction C. only the center D. a scale factor Answer: B
An enlargement with center the origin and scale factor 2 sends (3, 1) to: A. (5, 3) B. (6, 2) C. (1.5, 0.5) D. (3, 2) Answer: B
