The vertical line test
1: Trapezoid
2: rectangle!
STEP BY STEP EXPLINATION
A right angle is exactly 90 degrees, so if the pentagon has 108 degree angles, it’s not a right Angle!
The parallelogram has 107 degree angles and 73 degree angles, it’s not exactly 90.
The trapezoid has two right angles! The two sides make a right angle at the vertex! So, it has a right angle!
Same thing for the rectangle!
HOPE THIS HELPS! HAVE A GREAT DAY!
