Question

on a quiz charlie reflected the triangle to below across the y-axis but it was marked wrong. Describe his error.​

Answer 1

Charlie is wrong because he moved the triangle over by one more space than he should've.

Explanation:

A reflection across the y axis is like reflecting off a mirror. It should have the same amount of space between each other to the y axis

Answer 2

For whatever reason, Charlie seems to have reflected the triangle correctly but then shifted it 1 unit more to the right.
