What else can I help you with?
Is a rectangle a parralelogram?
yes a rectangle is a parralelogram because it has four parralel lines and has four right angles
What is a parralelogram with opposite sides equal and four right angles?
A rectangle
Does a parralelogram have four equal angles?
No, unless they're all right angles. Otherwise it has two pairs of equal angles.
How many angles must a parralelogram have?
four, well two pairs of angles (they're matched
What shape has exactly one pair opposite angles that are congruent?
A parralelogram
Can parralelogram bisect each other at right angle?
If you mean parallelograms (not parralelogram), the answer is yes, it is possible but very unlikely.
How many semmety lines does a parralelogram have?
None.Also a parallelogram (not parralelogram!) has no lines of symmetry (not semmety!)
How many sides does a parralelogram?
Four
How many angles and how many right angles in a square?
4 right angles, no other angles.
To make sure a parralelogram is a rectangle how many angles need to be 90?
If one angle of a p/gram is 90o, the other three MUST also be 90o. (In a p/gram each pair of adjacent angles total 180o)
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.
Does a parralelogram have adjacent sides that are equal?
It can, but it doesn't have to.If it does, then it's a special parallelogram, called a "rhombus".If the rhombus has right angles inside, then it's a special rhombus, called a "square".Both of these things are still parallelograms.
