This quadrilateral is defined by having all right angles.
Rectangle
True of False: All regular polygons have congruent angles.
True. They also have all congruent sides.

Which of the following words is not a parallelogram: Rectangle, Rhombus, Square, Trapezoid
Trapezoid
A 30-gon is a polygon with 30 sides. If we assume this figure is regular, then what is the measure of both its interior angle sum and the measure of each interior angle?
Interior Angle Sum = 5,040 degrees.
Where each Interior Angle = 168 degrees.
