Does some parallelograms have 4 right angles?
Yes a rectangle for example
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.
There are some parallelograms which are not rectangles true or false?
yes. rectangles are just the special cases of parallelograms where the angles are all 900
What is true of rectangles that isn't true of parallelograms in general?
All rectangles have 90 degree angles and with parallelograms that does not always have to be the case. But no matter what in order for a parallelogram to be a rectangle the angles have to all be 90 degrees.Rectangles are special cases of parallelograms. They have all the properties of parallelograms, and in addition, all their internal angles are right-angles - 90° angles.
Will a parallelogram always sometimes or never be a square?
Some parallelograms are squares - the ones which are equiangular (have equal angles) and are equilateral (have equal side lengths). All squares are parallelograms, but only some parallelograms are squares.
Which best describes the angles of a parallelogram?
which beat describes the angles of some parallelograms
If two parallelograms are similar then the corresponding angles are what?
If two parallelograms are similar then the corresponding angles are EQUAL.
Opposite angles of all parallelograms are always?
opposite angles of all parallelograms are always equal.

All rectangles are parallelograms. are all parallelograms rectangles explain.?
All parallelograms are not rectangles. The angles of a parallelogram need not be right angles and so the figure need not be a rectangle.
Is it true some rectangles are not parallelograms?
No. All rectangles are parallelograms, specifically those with two pair of parallel sides and all right angles.
Do parallelograms have no congruent angles?
Parallelograms normally have 2 congruent obtuse angles and 2 congruent acute angles that altogether add up to 360 degrees
Are rectangles are parallelograms?
Parallelograms do not have right angles. A rectangle is a parallelogram but a parallelogram is not a rectangle.
