Question

On a coordinate plane, polygon GHIJ translates 8 units to the left to form polygon G'H'I'J'. Which of the following equations is not necessarily true?

Answer 1

It's D: m∠HI'J = m∠H'IJ'

Explanation:

Answer 2

When you translate a figure, none of the lengths change and none of the angles change. The only equation you listed that does not equate two translated lengths or two translated angles is G'H' = 8 units. There is nothing in the statement of the problem that requires this to be true.
