A parallelogram doesn't necessarily have any perpendicular sides, but it can. If it has one single 90-degree angle, then it has four of them, and it's a rectangle. Apexvs geometry 2nd sem -- false.
It is a rhombus. All four sides have the same length and the diagonals are therefore perpendicular.
"It has four sides" is a description that does not guarantee that a quadrilateral is a square.
Yes. A rhombus has parallel sides. All sides are also congruent, and the diagonals are perpendicular to each other. The rhombus is a special kind of parallelogram, so in addition to all the propeties of a parallelogram, it also has a few properties of its own.
A rhombus is a parallelogram with all 4 sides congruent. The diagonals bisect(split in have) the interior angles. The diagonals are perpendicular to each other.
By definition, a parallelogram two separate pairs has parallel sides. The only type of parallelogram that has perpendicular sides is a rectangle. All others have non-perpendicular sides.
No. A parallelogram has two parallel sides.
A parallelogram doesn't necessarily have any perpendicular sides, but it can. If it has one single 90-degree angle, then it has four of them, and it's a rectangle or square. A parallelogram without perpendicular sides is a rhomboid or rhombus.
No. Not necessarily.
Parallelogram.
Not normally but as a rectangle it has perpendicular sides that meet at right angles
100
No.
A rectangle
Only in the special case when the parallelogram is a rectangle
