Are all parallelograms a rectangle?
No, because to have a rectangle, you need to have four right angles, and parallelograms dont have to have right angles. However, all rectangles are parallelograms.
What is all parallelograms with four right angles?
Squares
How many right angles in a parellelogram?
Generally, there are no right angles in a parallelogram, but rectangles and squares can be seen as special parallelograms, as they have all the qualities needed to be classed as parallelograms, and in addition, they have four right angles.
The opposite sides of a parallelograms with four right angles is a?
It's a rectangle
Are rectangles special kinds of paraelleograms?
Yes, they are parallelograms with four right angles.
Are rectangles parallelograms?
Yes, rectangles are a special case of parallelogram, with four right angles.
All parallelograms with four right angles are?
Rectangles, because a square can be a rectangle, but a rectangle can't be a square.
How do I know my parallelogram is not a rectangle?
A rectangle - has four right-angles at the corners. A Parallelogram - has no right-angles, but has opposite angles equal. Technically - a rectangle is a parallelogram, but a parallelogram can never be a rectangle. Clarification - Actually, all rectangles are parallelograms, but not all parallelograms are rectangles. The definition of a parallelogram is that of a four-sided shape where the opposite sides are parallel. There is no angle-size limitation in the definition. Squares, rectangles and rhombuses are all parallelograms.
What is a parallelogram where all 4 sides are equal and the opposite sides are parallel?
All "parallelograms" have opposite sides that are parallel. If all four sides have an equal length and the angles are not all right angles, it is a rhombus. If there is any right angle, then they are all right angles and the parallelogram is a square.(note : it is not possible for a quadrilateral to have four equal sides without being one of these parallelograms.)
What is every rectangle?
Every rectangle has four (straight) sides, and four (right) angles. All rectangles are also polygons, quadrilaterals, and parallelograms.
Can a rhombus be a parallelogram?
All rhombuses are paralleleograms. Rhombuses are parallelograms in which all four sides are the same length (and the opposite angles are congruent). Squares are rhombuses in which all four angles are right.
If all rectangles are parallelograms are all squares parallelograms?
Yes. Squares are just complex rectangles, as the definition of a rectangle is that it has four right angles with opposite sides being parallel.
