Do all the angles in a rectangle add up to 360?
Does a rectangles angles add up to 180?
What angles make up a rectangle?
- It must have four sides.
- All four angles must be 90 degree right angles.
- A rectangle is a special case of a parallelogram; its opposite sides are parallel. …
- The diagonals of a rectangle are equal in length to each other and they bisect each other at their point of intersection.
How do angles add up to 360 degrees?
For any quadrilateral, we can draw a diagonal line to divide it into two triangles. Each triangle has an angle sum of 180 degrees. Therefore the total angle sum of the quadrilateral is 360 degrees.

What is the sum of four angles in a rectangle?
Proof: This follows directly from the Quadrilateral Sum Conjecture which says that the sum of angles in any convex quadrilateral is equal to 360 degrees. Since a rectangle has four angles of equal measure, the measure of each must be 360/4, or 90 degrees.
