Is a rectangle a parralelogram?
yes a rectangle is a parralelogram because it has four parralel lines and has four right 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)
What shape has exactly one pair opposite angles that are congruent?
A parralelogram
What is a parralelogram with opposite sides equal and four right angles?
A rectangle
How many semmety lines does a parralelogram have?
None.Also a parallelogram (not parralelogram!) has no lines of symmetry (not semmety!)
Is a rectangle a parralelogram?
yes a rectangle is a parralelogram because it has four parralel lines and has four right angles
How many right angles does a parralelogram have?
If it has any, it's a rectangle (or in some instances, a square)
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)
What is a parralelogram with opposite sides equal and four right angles?
A rectangle
What shape has exactly one pair opposite angles that are congruent?
A parralelogram
Does a parralelogram have four equal angles?
No, unless they're all right angles. Otherwise it has two pairs of equal angles.
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
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.
Is an equilateral Triangle a parralelogram?
No.
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 of its angles must measure 90 on a rectangle?
All four angles of a rectangle must equal 90 degrees each.
