a square as it is the only parallelogram with all four sides of equal length and all four angles are right angles
Not necessarily. A parallelogram is a quadrilateral with 2 sets of 2 parallel sides. Only rectangles and squares have right angles as all four angles - a rectangle is a "special" parallelogram that has all four angles equal; a square is a "special" rectangle that has all four sides of equal length.
a rhombus is a parallelogram with 4 equal sides. It does not need right angles; that is a special case which is a square
There are no right angles in a parallelogram. A parallelogram only has right angles if it is a rectangle, in which case it has exactly four.
A square is a special form of a parallelogram. A parallelogram is a quadrilateral with four sides, and two sets of parallel sides. A rectangle is a special case of parallelogram that has four right angles. A square is a special case of rectangle, in that a square has four equal sides as well as the four right angles.
A parallelogram with no right angles and four congruent sides is a Rhombus.
A parallelogram:is a quadrilateral (a four sided polygon)has opposite sides parallel and of equal lengthhas opposite angles equalThe area of a parallelogram is calculated by multiplying one side length by the perpendicular distance between that side and the side parallel to it. A rectangle is a special parallelogram in that all four angles are equal and are right angles (90°).A rhombus is a special parallelogram in that all four sides are of equal length.A square is a special parallelogram in that all four angles are equal (and are right angles) and all four sides are equal in length.
A parallelogram does not have to be four right angles. A parallelogram is a four sided shape with two parallel lines.
Yes, rectangles are a special case of parallelogram, with four right angles.
A rectangle is a parallelogram with four right angles.
