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

Answers

Answer 1

Answer: no, if you were to have three right angles, then the fourth angle would also have to be a right angle. This would make the shape either a square or a rectangle, not a trapezoid.

Answer 2

Answer: No, because a trapezoid is defined as a quadrilateral with EXACTLY one pair of parallel sides (the other two cannot be parallel). Because the sum of the angles in a quadrilateral sum up to 360°, and three of the angles are each 90°, that means the fourth angle must equal (360 - 3(90)) = 90°, so therefore this figure would be a rectangle, not a trapezoid.

Answers

9 sq. units refers to a 2d figure
9 cubed units refers to a 3d figure

so
9*9 would be sq. unit cuz dimensions of square
9*9*9 would be cubed unit cuz dimensions of cube
so in simple, 9^2,
and 9^3

9 square units is basically 9 to the second power (9^2) while 9 cubic units is 9 cubed (9^3)
