They are all 90
Ninety degrees.
A rectangle. If the sides are the same size, it's a square.
All four angles in a rectangle are 90 degrees. In any quadrilateral the sum of all four angles is 360 degrees.
They can, but usually they are not. All the angles will be equal only if your parallelogram is a rectangle.
An equilateral triangle, a square, a rectangle, an octagon.
Ninety degrees.
No. All rectangles have 4 interior angles each measuring 90 degrees.

It will always be one. If all angles are congruent, there will be four right angles, forming a rectangle. A rectangle is also a parallelogram.It will always be one. If all angles are congruent, there will be four right angles, forming a rectangle. A rectangle is also a parallelogram.It will always be one. If all angles are congruent, there will be four right angles, forming a rectangle. A rectangle is also a parallelogram.It will always be one. If all angles are congruent, there will be four right angles, forming a rectangle. A rectangle is also a parallelogram.
In a rectangle, all the opposite sides, and angles are congruent to each other. All 4 angles of the rectangle, are right angles.
The diagonals of a rectangle bisect the angles only if the rectangle is a square.
