well accoring to my calculations the angle sum of a quadrilateral is equal to the sum of 360 degress the way u do this is u find the exterior angles of one side of a quuadrilateral and do it for all the other sides if you have any other questions please post it to a new site call www.freewebs.com/1pkc thankyou we are more than welcome to help u
Rectangles;all angles equal 90 degrees
No but as a 4 sided quadrilateral its 4 interior angles add up to 360 degrees
A parallelogram is a geometric quadrilateral with two pairs of parallel sides. The opposite sides and opposite angles are equal in length.
Yes because a parallelogram is a quadrilateral and the sum of its interor angles is 360 degrees.
The exterior angles of polygons equal 360 degrees.
No. Only the sum of the measures of the angles of a triangle equal to 180 degrees; in the case of a quadrilateral it amounts to 360 degrees.
The sum of all inside angles of a quadrilateral equal 360 degrees.
Yes. It is a quadrilateral with right angles and opposite sides equal.
All four interior angles in a quadrilateral add up to 360 degrees
Angles are measured in degrees, not sides.
Their sum does.
With quadrilaterals, if there are three equal angles, then we know that the fourth angle must be equal, so the quadrilateral is a rectangle. * * * * * That is absolute rubbish. You can have a quadrilateral with three angles of 70 degrees and the fourth of 150 degrees. There is no name for such quadrilaterals and the only thing that can be said about them is that they are irregular.
Rectangles;all angles equal 90 degrees
The 4 interior angles add up to 360 degrees
no angles are equal so no sides can be equal or parallel. Its just a quadrilateral.
This can only be a square: All 4 sides are equal, and all angles are equal to 90 degrees.
The sum of all the angles of a quadrialateral, whether its regualr or irregular is 360 degrees.
