Yes.
No because the 4 interior angles of a quadrilateral add up to 360 degrees
That depends on the quadrilateral. They will not all have the same measure. Even rectangles will not all have the same central angle measures.
90 degrees.
90 degrees
There are only 4 possible numbers which could be measures of the angles for the quadrilateral. Each of the infinitely many other measures, such as 36.57 degrees, could NOT be the measure.
Yes as for example a square has 4 interior equal angles of 90 degrees.
Yes
That will depend on what type of 4 sided quadrilateral it is but its 4 interior angles add up to 360 degrees.
The sum of the exterior angles of a polygon equals 360.Quadrilateral has 4 exterior angles.360/4=90 for a regular quadrilateral.
It is possible, but parallelograms do not. Some quadrilaterals do.
Each exterior angle of a square is 90 degrees and a square is a regular 4 sided quadrilateral
A rectangle or a square.
