Answer:
5. F, G, L, and A are the vertices.
6. 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.
7. No. A trapezoid is a quadrilateral, and therefore must have an interior angle sum of 360 degrees. Any obtuse angles must be offset by acute ones, unless they’re all right angles/it’s a rectangle.
91 + 91 + 91 + 91 = 364 > 360.
An obtuse angle always lies between 90° and 180°.
