Question

Can a trapezoid habe 3 right angles?

Answer 1

Nope.

Explanation:

A trapezoid is a quadrilateral with only 1 pair of parallel sides. Since a quadrilateral has 360 degrees and 4 angles, and right angles are 90 degrees, the measure of the fourth angle is
`360-3(90)`, or 90 degrees. Since the resultant figure has 4 right angles, its opposite sides must be parallel, so it cannot be a trapezoid.
