Are the opposite angles of a paralellogram equal?
Yes
What do the angles of a paralellogram add to equal?
They equal 360 degrees.
What angles does a paralellogram have?
It has two pairs of angles. Each pair of opposite angles is equal.
What quadilateral has 4 equal sides but 4 angles are not equal?
A Rhombus or a paralellogram or what is known as a "diamond-shape", like on a playing card. These would fit the criteria given - They are all names for a quadrilateral with four equal sides with non-equal angles.
When is a paralellogram a revtangle?
A parallelogram is a rectangle when all of its angles are right angles (90 degrees). In other words, if the opposite sides of a parallelogram are equal in length and all angles measure 90 degrees, it is a rectangle.

Are parallelograms squares?
yes because a paralellogram has two sets of paralell sides and a square does too and opposite sides are equal in length and opposite angles are congruent yes because a paralellogram has two sets of paralell sides and a square does too and opposite sides are equal in length and opposite angles are congruent
How Dow you that the opposite angles of a parallelogram are equal?
First of all, you know the opposite sides of a parallelogram are equal because of the definition of a parallelogram. Therefore, two adjacent angles in the parallelogram are supplementary, because same-side interior angles in two parallels and a transversal are always supplementary. Therefore, opposite angles in a paralellogram are equal, because two angles both supplementary to a third angle are equal to each other.
What is the sum of adjacent angles in a paralellogram?
180 degrees.
What is a paralellogram with all sides congruent?
A rhombus if it has no right triangles, and a square if all the angles are right. The basic answer is a rhombus or square.
What is the difference between a paraLellogram and a rectangle?
A rectangle is a special case of a parallelogram in which all the interior angles are 90 degrees.
A paralellogram with 4 right angles and 4 congruent sides?
A square
How many right angles are in a paralellogram?
If the parallelogram is a square or a rectangle, then there are four right angles, otherwise there are none.
