Are the opposite sides of a parallelogram congruent?
PARALLELOGRAMS (rectangles, squares, and rhombi): 1) Opposite sides of a parallelogram are congruent. 2) Opposite angles of a parallelogram are congruent.
What are opposite angles in a parallelogram called?
The opposite angles of a parallelogram are equal. The consecutive angle of a parallelogram is supplementary. If one angle is a right angle, all the angles are right angles in a parallelogram. The diagonals of a parallelogram bisect each other.
What is a congruent parallelogram?
There are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then all angles are right.
Do all parallelograms have 4 right angles?
In a parallelogram, if one of the angles is a right angle, all four angles must be right angles. If a four-sided figure has one right angle and at least one angle of a different measure, it is not a parallelogram; it is a trapezoid.
How are the opposite sides of a parallelogram congruent?
It is a quadrilateral where both pairs of opposite sides are parallel. There are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B).
How many parallel sides are there in a parallelogram?
A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length and the opposite angles are equal in measure.
What are the properties of a quadrilateral parallelogram?
It is a quadrilateral where both pairs of opposite sides are parallel. There are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°).
Which is a special kind of Polygon called a parallelogram?
One special kind of polygons is called a parallelogram. It is a quadrilateral where both pairs of opposite sides are parallel. There are six important properties of parallelograms to know: Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B).
