Question

Alexi transformed figure L such that its image is figure K after a 90degree counterclockwise rotation about the origin and a reflection over the y-axis.

On a coordinate plane, triangle K has points (negative 3, 1), (negative 1, 2), (negative 2, 5). Triangle L has points (2, negative 1), (1, negative 3), (5, negative 2).

Jonathan used figure L to perform the same transformation, but he reflected figure L over the y-axis before performing the 90degree counterclockwise rotation. Which best compares Alexi’s and Jonathan’s transformed figures?
The change in order will not affect the final image. Their transformed figures will be identical.
The change in order will result in the transformed images having vertices in the same location, but in a different orientation.
The change in order will result in the transformed image of figure L being transformed back onto figure L.
The change in order will result in the transformed image of figure L having a different location.

Answer 1

The best answer that compares Alexi’s and Jonathan’s transformed figures is; The change in order will result in the transformed image of figure L having a different location.

How to Identify Transformations?

A 90degree counterclockwise rotation about the origin is depicted by; (x, y) → (-y, x)

Now, the rule for a reflection over the y -axis is (x, y) → (−x, y) .

This means that the transformation of Alexis will first go through (x, y) → (-y, x) and then finally (x, y) → (−x, y) .

Now, Jonathan uses triangle L to perform same transformation as Alexis but he reflected over the y-axis first. Thus, the best comparison of both transformations is that The change in order will result in the transformed image of figure L having a different location.
