Do some rectangles have no right angle?
No, all four angles with in a rectangle are right angles.
What quadrilaterals have all four angles congruent?
squares, rectangles, some rhombuses .... I'm not sure all angles can be congruent
Do quadrilaterals have right angles?
"Quadrilateral" simply means "four sided". Some quadrilaterals do have right angles; squares or rectangles, for example. Some have one or two right angles, but some don't have any right (90 degree) angles.
Why does a rectangle not have four equal sides and four right angles?
Some rectangles do. We call those rectangles squares. There's not a "why", really, unless you want to get into etymology, in which case this question should be in language categories and not math categories.
What do all rectangles have that some parallelograms do not have?
Rectangles have 4 rift angles and some parallelogram doesn't have 4 right angles. Only two parallelogram has 4 right angles , square and rectangle
Do some rectangles have no right angle?
No, all four angles with in a rectangle are right angles.
Are some rectangles are rhombuses?
Yes. The reason why is because a rectangle is a quadrilateral with four right angles and a rhombus can have four right angles and it is also a quadrilateral.
What quadrilaterals have all four angles congruent?
squares, rectangles, some rhombuses .... I'm not sure all angles can be congruent
Is it true that Some parallelograms are rectangles?
A parallelogram is a four sided figure. that has congruent angles and all sides are parallel
Are some rhombuses rectangles?
Yes. The reason why is because a rectangle is a quadrilateral with four right angles and a rhombus can have four right angles and it is also a quadrilateral.

Rectangles have 4 rift angles and some parallelogram doesn't have 4 right angles. Only two parallelogram has 4 right angles , square and rectangle
Are rectangles also parallelograms?
A rectangle must have four right angles in addition to two pairs of parallel edges. So some rectangles are parallelograms but not all are.
What are some polygons with right angles that are parallelogram?
Squares and rectangles.
What is a perpendicular shape?
A perpendicular shape is one where either one or more or even all of the angles are right angles. Some examples are rectangles and squares.
Are all rectangles squares?
No. A square must be a rectangle, but a rectangle does not have to be a square.A square is a rectangle that has four sides of equal length.--A rectangle MUST have the following:Four sidesFour angles that are right angles (90 degrees), so that the total is 360 degrees.Two pairs of parallel sidesTwo pairs of equal sidesA square MUST have the following:Four sides (All must be the same length)Four angles(Must all be 90 degrees)Two pairs of parallel sidesBecause of that not all rectangles are squares but all squares are rectangles.---Rectangles are parallelograms with all right angles, and opposite sides are congruent. Squares are parallelograms with all right angles, and ALL sides congruent. Therefore, all squares are rectangles, but not all rectangles are squares.False! squares have 4 equal sides and rectangles don't they only have 2 equal sides. Some rectangles are squares, but not all of them. On the other hand, all squares are rectangles.
