6.2-6.3: Parallelograms: Transcript

Objectives Be able to use some properties of parallelograms Be able to prove that a quadrilateral is a parallelogram Parallelograms A parallelogram is a quadrilateral with both pairs of opposite sides parallel. Section 8.5. Goal. Find the area of parallelograms.. Key Vocabulary. Base of a parallelogram. Height of a parallelogram. Parallelogram. Rhombus . Parallelogram. A parallelogram is a quadrilateral where the opposite sides are congruent and parallel.. The area of a parallelogram is base x height.. 8cm. 5. cm. Area = 8 x 5 = 40cm. 2. Here’s why:. A parallelogram can be split up into a rectangle and 2 triangles – each with the same area.. 10cm. Quadrilaterals. Quadrilaterals. Parallelograms. Quadrilaterals. Parallelograms. Rectangles. Rhombi. Quadrilaterals. Parallelograms. Rectangles. Rhombi. Squares. Quadrilaterals. Parallelograms. Rectangles. “…geometric shapes are the alphabet in which the book of nature is written." -Galileo.

Recognize and apply the properties of rhombi and squares.. Determine whether quadrilaterals are rectangles, rhombi, or squares.. Properties of a rhombus. A rhombus is a parallelogram with all four sides congruent.. Lesson 7.2 Properties of Parallelograms Learning Target: Prove and use properties of parallelograms. Success Criteria: I can prove properties of parallelograms. I can use properties of parallelograms. I can solve problems involving Parallelograms Quadrilaterals are four-sided polygons Parallelogram: is a quadrilateral with both pairs of opposite sides parallel. Parallelograms (2) Theorem 6.1 : Opposite sides of a parallelograms are congruent Theorem 6.2: Opposite 7.2 – Properties of Parallelograms Today you will learn how to use properties to find side lengths and angles of parallelograms, and use parallelograms in the coordinate plane. Using Properties of Parallelograms A parallelogram is a Math 9 Properties of Parallelograms Properties of Parallelograms > > parallelogram Opposite sides of a parallelogram are parallel. The opposite angles of a parallelogram are congruent. The opposite sides of a parallelogram are congruent.
