4 angles.
Quadrilaterals have exactly four angles.
The exterior angles of any polygon are as many as their sides.
All quadrilaterals have consecutive and opposite angles.
The 4 interior angles of 4 sided quadrilaterals add up to 360 degrees The exterior angles of any polygon add up to 360 degrees
The sum of the exterior angles of all polygons equals to 360⁰.Since only the sum of the interior angles of all quadrilaterals equals to 360⁰, the polygon must have 4 sides.
They are both polygons and their exterior angles add up to 360 degrees
They are both quadrilaterals and they both have interior and exterior angles of 360 degrees.
4 angles.
Quadrilaterals have exactly four angles.
1080 degrees (an average of 270 degrees, times the four angles).
ALL quadrilaterals have 4 angles
The exterior angles of any polygon are as many as their sides.
All quadrilaterals have consecutive and opposite angles.
Quadrilaterals have 4 sides, 4 angles, and 4 vertices.
All quadrilaterals have diagonally adjacent angles.
There are eight interior angles, and 16 exterior angles.
