Does a parallelogram have equal angles?
Yes, the opposite interior angles of a parellelogram are equal.
Is a parellelogram a regular polygon?
No, If all angles are equal and all sides are equal, then it is a regular polygon (otherwise it is 'irregular'). In this case, parallelogram is irregular.
Why are the opposite angles in a parellelogram equal?
Because they are angles that are subtended by pairs of sides that are parallel to each other. There are several ways of proving the angles are equal.
A parellelogram with all sides and all angles congruent?
square.......
What is a parellelogram with four congruent sides?
A parallelogram with equal sides is a rhombus. If the interior angles are right angles, it's a square.
Are the opposite sides of a parellelogram parallel?
Yes. A parallelogram is defined as having opposite sides that are parallel and equal in length, and opposite angles that are equal.
What figure is 2 dimensional with two pairs of parallel sides has no right angles and all sides are the same length?
A rhombus. More information... The no right angles is throwing me, but I will add this comment: A square A four-sided polygon having equal-length sides meeting at right angles. The sum of the angles of a square is 360 degrees. A Parellelogram is a four-sided polygon with two pairs of parallel sides. The sum of the angles of a parallelogram is 360 degrees. A Rhombus is a four-sided polygon having all four sides of equal length. The sum of the angles of a rhombus is 360 degrees. So, a Square is actually a Parellelogram and Rhombus as well; and it has 4 right angles. So... I am not sure that Parellelogram and Rhombus are what you were looking for,
What is a parellelogram with 4 right angles?
It is a rectangle
What is a parellelogram with four right angles?
rectangle
Are all squares parellelograms?
A square is parellelogram because all the sides are equal.
Is a square a parellelogram?
A square is always a parellelogram since it has equal sides.
Is a rectangle a parellelogram?
yes, a rectangle is a parallelogram with right angles.
