The angles formed by two consecutive sides of a polygon are called interior angles. These angles are located inside the polygon and are created where two sides meet at a vertex. The sum of the interior angles of a polygon depends on the number of sides it has, calculated using the formula (n - 2) × 180°, where n is the number of sides. Each interior angle can vary in measurement based on the type of polygon (e.g., triangle, quadrilateral).
A cow
Not necessarily. It is a side only if the two vertices it connects are consecutive.
square
the pairs of angles on one side of the transversal but inside the two lines.
a right angle, a obtuse angle, and an acute angle.
They form a vertex of the polygon.

A cow
either an obtuse, acute, or right angle
