Does a parallelogram have four 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.
How are squares and parallelograms different?
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.
How parallelogram with four equal sides but no right Angles?
a rhombus is a parallelogram with 4 equal sides. It does not need right angles; that is a special case which is a square
How many right angles are in a parallelogram?
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.
Are rectangles parallelograms?
Yes, rectangles are a special case of parallelogram, with four right angles.
A parallelogram with no right angles an four congruent sides?
A parallelogram with no right angles and four congruent sides is a Rhombus.
What is a special kind of parallelogram?
a square as it is the only parallelogram with all four sides of equal length and all four angles are right angles
Is a parallelogram always have 4 right angles?
A parallelogram does not have to be four right angles. A parallelogram is a four sided shape with two parallel lines.
Can arectangle be a rhobus?
Yes. A rectangle is a parallelogram with four right angles. A rhombus is a parallelogram with four equal sides. Therefore, if a rectangle has four equal sides, then it is a rhombus. If a rhombus has four right angles, it is a rectangle. In this case, the rectangle and the rhombus are a special type of parallelogram called a square.
How many right angles does a parallelogram?
A parallelogram doesn't need any right angles in order to be a parallelogram.If it has any, then it's a special kind of parallelogram, called a "rectangle".Note:The way the properties of a parallelogram work out,if it has one right angle, then it has four of them.
What is a parallelogram with 1 right angle?
A parallelogram cannot have just one right angle. If it has one, all four of its angles must be right angles and so it must be a rectangle (or, as a special case, a square).
What has 4 congruent and no right angles?
A rhombus is a parallelogram with all four sides congruent to each other with no right angles. A square is a parallelogram with four congruent sides and four right angles.
