Chapter 4 Unit TEST: Transfomations

Question 1

On a coordinate plane, 2 rectangles are shown. Rectangle P Q R S has points (1, 1), (1, 5), (3, 5), (1, 5). Rectangle P double-prime Q double-prime R double-prime S double-prime has points (negative 1, negative 1), (negative 5, negative 1), (negative 5, negative 3), (negative 1, negative 3).

Revolt · Accepted Answer

Reflected across the y-axis composition 270 degree rotation about point 0.

Question 2

2 triangles have identical side lengths and angle measures. The second triangle is rotated slightly to the left.

Revolt · Accepted Answer

It is rigid because all side lengths and angles are congruent.

Question 3

A line segment has endpoints at (–1, 4) and (4, 1). Which reflection will produce an image with endpoints at (–4, 1) and (–1, –4)?

Revolt · Accepted Answer

a reflection of the line segment across the line y = –x

Question 4

2 right triangles have identical angle measures but different side lengths. The first triangle has side lengths of 6, 10, 8 and the second triangle has side lengths of 3, 5, 4.

Revolt · Accepted Answer
