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

A square and a rectangle for example.
An equilateral triangle, a square, a rectangle, an octagon.
In a rectangle, all the opposite sides, and angles are congruent to each other. All 4 angles of the rectangle, are right angles.
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.
The diagonals of a rectangle bisect the angles only if the rectangle is a square.
