Parallelograms have Properties Click to view What is a parallelogram? A parallelogram is a quadrilateral with both pairs of opposite sides parallel.

Midsegments of a Triangle

Let’s review the quadrilateral properties we’ve learned so far:

Rhombus 1.Both pairs of opposite sides are parallel 2. Both pairs of opposite sides are congruent 3. Both pairs of opposite angles are congruent 4. Consecutive.

Proofs with Quadrilaterals. Proving Quadrilaterals are Parallelograms Show that opposite sides are parallel by same slope. Show that both pairs of opposite.

Properties of Quadrilaterals

A D B C Definition: Opposite Sides are parallel.

Date: Topic: Trapezoids and Kites (7.3) Warm-up: A B C D ABCD is a rectangle. 30 Perimeter = 80 Opposite sides of a rectangle are congruent. 2 2.

6.3 Proving Quadrilaterals are Parallelograms. Theorem If both pairs of opposite sides of a quadrilateral are parallel, then it is a parallelogram.

Properties of a trapezoid ♥ A trapezoid has one and only one pair of parallel sides. ♥ Two pair of consecutive, supplementary angles.

Properties of a TRAPEZIUM: A quadrilateral with NO parallel sides. ♥ 2 pair of consecutive congruent sides ♥ Opposite sides are NOT congruent ♥ Only ONE pair of opposite angles are congruent. ♥ Diagonals are perpendicular ♥ Only ONE diagonal is bisected A special Trapezium is a KITE
