a square
parallelogram
No, it does not. But an angle and the angle opposite it are always equal.
square
yes every parallelogram has at least 1 right angle
A parallelogram with at least one right angle
A rectangle is a parallellogram with one right angle; A parallelogram is a quadrilateral with opposite sides equal and parallel.
In general, no. Not unless the parallelogram has at least one right angle.
TRUE.A rectangle is by definition a parallelogram. A parallelogram is a quadrilateral with 2 pairs of parallel lines. A rectangle is a parallelogram with 4 equal angles which are 360o/4 = 90o.The opposite angles of a parallelogram are equal as well. Therefore the following is true.If one angle is equal to 90o then the opposite angle is 90o. That leaves two angles and 180o. Since the two angles left are equal then they are each 180o/2 which is also 90o.
Yes a parallelogram with a right angle is a square.
parallelogram in general, and a rhombus also, which is a type of parallelogram
No, but a square is a parallelogram (with one right angle and adjacent sides equal)
A parallelogram is a figure with different lengths and widths(also called breadth) where opposite sides and opposite angles are equal. But the angles are not 900 each. In fact, no angle in a parallelogram is a right angle as presence of 1 right angle proves all the angles to be right angles. A parallelogram with 4 right angles is called as a ''rectangle''
