Question

The angles of a quadrilateral measure 80, 100, 100, and 80 in this order. What kind of quadrilateral has this shape? How do you know?

Answer 1

It is a rectangle because with a rectangle each pair of parallel sides have the same length. I hope this helps.

Answer 2

"The answer is isosceles trapezoid.

If two obtuse angles are next to each other (100° and 100°) and followed by two acute angles next to each other as well ((80° and 80°), the shape is trapezoid. Trapezoid is quadrilateral shape that has a pair of parallel sides parallel. When angles on each of its base are equal, trapezoid is called isosceles trapezoid."
