They can, they do, they have to.
All of them, except rectangles. (Rectangles are special parallelograms.)
No, all four angles with in a rectangle are right angles.
Yes. Rectangles have four right angles.
No, only squares and rectangles have 4 right angles.
True. All rectangles are parallelograms because they have opposite sides that are equal and parallel, and their angles are all right angles. This satisfies the definitions of both shapes, making every rectangle a specific type of parallelogram. However, not all parallelograms are rectangles, as parallelograms can have angles that are not right angles.
Rectangles have four sides and four angles.
a rectangle has 4 right angles. A rhombus has four congruent sides. A square has four right angles and four congruent sides. All squares are rectangles because all rectangles have 4 right angles, and all squares have four right angles. But not all rectangles are squares because not all rectangles have congruent sides.
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
All of them, except rectangles. (Rectangles are special parallelograms.)
No, all four angles with in a rectangle are right angles.
Yes. Rectangles have four right angles.
yes.
yes, all rectangles have right angels.
No because rectangles have to have right (90 degree) angles.
No, only squares and rectangles have 4 right angles.
all angles are right angles
No. Only rectangles, which includes the square, have 4 right angles
