What is quadrilateral with equal adjacent angles called?

A quadrilateral with equal adjacent angles is called a rectangle. In a rectangle, each angle measures 90 degrees, and adjacent angles are equal. This property distinguishes rectangles from other quadrilaterals, such as rhombuses or parallelograms, where angles may not be right angles.

What are two angles called whose sum is 180 degrees?

Two angles whose sum is 180 degrees are called supplementary angles. When two angles are supplementary, it means that the sum of their measures equals 180 degrees. This relationship is often used in geometry to solve for unknown angles or to identify complementary angles.
