Question

on a coordinate plane triangle XYZ is rotated 90 degrees counterclockwise about the origin to form triangle XYZ which conclusion is always true

Answer 1

Given a 90° rotation of triangle XYZ, every segment will rotate 90°, meaning that each segment will form a right angle with the corresponding transformed segment.

Thereby, the correct answer is:

`\bar{YZ}\perp\bar{Y^(\prime)Z^(\prime)}`

Answer B
