Parallelogram with 4 right angles?
rectangle
Are all angles of a parallelogram equal to 90 degrees?
No, only in a square (regular parallelogram).The opposite angles are EQUAL in a parallelogram, and the adjacent angles are SUPPLEMENTARY(they equal 180 degrees).So if any angle in a parallelogram is a right angle, they all are. Otherwise, there are no right angles.The angles of a parallelogram will average 90 degrees, as there are 360 degrees in any quadrilateral, (360/4 - 90) and 180 degrees in two adjacent non-equal angles (180/2 = 90).
It has 4 sides all of its sides are equal all of its angles are right angles?
No, not necessarily. A parallelogram can have all sides equal, but still not be a square.
Do all parallelograms have 4 right angles?
no. the common parallelogram that looks like a slightly collapsed square/rectangle has angles around 45 degrees.
What is the name of a shape that has 4 sides and 4 right angles?
The shape is all of the following: -- quadrilateral -- parallelogram -- rectangle -- rhombus -- square
