Question

Which of the following describes the transformation of triange ABC shown in the diagram below

Answer 1

Reflection over the y-axis.

1) Let's start by locating each coordinate from the Pre-image and the Image:

Pre-image Image

A (1,1) A'(-1,1)

B (5,1) B' (-5,1)

C (4,4) C' (-4,4)

2) As each coordinate from the Image has the x-coordinate opposite to the Pre-image's x-coordinate we can state that the transformation performed was:

Reflection over the y-axis.
