Yes, opposite angles of a parallelogram are congruent.


In a quadrillateral consecutive and oposite angles are congruent What is the name of this figure?

A quadrilateral with consecutive and opposite angles that are congruent is called a parallelogram. In a parallelogram, opposite angles are equal, and consecutive angles are supplementary, meaning they add up to 180 degrees. This property distinguishes parallelograms from other quadrilaterals. Examples of parallelograms include rectangles, rhombuses, and squares.

Are angles and sides of a parallelogram congruent?

In all parallelograms, opposite angles and opposite sides are congruent. If all four sides are congruent, it's a rhombus. If all four angles are congruent, it's a rectangle. If all four sides and all four angles are congruent, it's a square.


What angles of a parallelogram are congruent?

What is a description of a parallelogram?

A parallelogram is a quadrilateral (4-sided figure) with both pairs of opposite sides parallel. That's usually the primary definition. There are properties common to all parallelograms: opposite sides are congruent, opposite angles are congruent, and diagonals bisect each other. Other special parallelograms have additional properties. A rectangle is a parallelogram with four right angles and its diagonals are congruent. A rhombus is a parallelogram with four congruent sides. Its diagonals are perpendicular and each diagonal bisects two angles of the rhombus. A square is a parallelogram as well. It has four right angles and four congruent sides, so it is also a rectangle and a rhombus. How's that for confusing???
