Yes- they are all right angles.
They can, but usually they are not. All the angles will be equal only if your parallelogram is a rectangle.
A rectangle is a parallelogram in which all four vertex angles equal 90°.
Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.
A square. * * * * * Or a rectangle.
Yes- they are all right angles.
yes......? they are all right angles.
Yes. All corners of a rectangle have 90 degree angles.
All rectangles are irregular and each has four equal angles.
A rectangle is only a square when all the sides are equal and all the internal angles are right angles.
They can, but usually they are not. All the angles will be equal only if your parallelogram is a rectangle.
Some of them are, but not all of them. A parallelogramis a rectangle only if all of its angles are equal.
A rectangle has four angles of 90° each, also known as right angles. The special case is the square, which is a rectangle with four equal sides.
A rectangle is a parallelogram in which all four vertex angles equal 90°.
Not unless all angles are also equal. A rhombus is a parallelogram with all sides equal. A rectangle is a parallelogram with all angles equal. A square is a rhombus with all angles equal which is a parallelogram with all sides equal and all angles equal.
Yes, because not all sides are equal but angles are. That's the key word "angles". It cannot be equal sides because a rectangle is not equal sided.
