Question

Kevin claims he can draw a trapezoid with three right angles. Is this possible? Explain.

I don't understand the problem at all

Answer 1

See below.

Explanation:

Kevin is incorrect.

Note that all four-sided polygons have a total amount of `360º`, and that every right angle is `90º`.

Knowing this, and going by Kevin's claim, we would already have `270º` with the three right angles. This only leaves us another `90º` angle, which is not possible in respect to forming a trapezoid.

For a quadrilateral to be a trapezoid, it can have only ONE set of parallel sides. If the quadrilateral had all angles being `90º`, there would be two sets of parallel sides, making it not a trapezoid, but a square, rectangle, etc.
