1
How are a square and a rhombus similar and different? square rhombus

2
In this lesson you will learn how to compare and contrast quadrilaterals by listing the attributes they share and those they don’t.

3
Let’s Review Quadrilaterals with 2 sets of parallel sides: square rectangle parallelogram rhombus 2 sets of parallel sides 2 pairs of congruent sides 2 sets of parallel sides 2 pairs of congruent sides 4 right angles 2 sets of parallel sides 4 congruent sides 4 right angles 2 sets of parallel sides 4 congruent sides

4
Let’s Review Quadrilaterals with 1 or less sets of parallel sides: trapezoid non-specific quadrilateral isosceles trapezoid 1 set of parallel sides 1 pair of congruent sides 4 sides

5
Let’s Review A Common Mistake Thinking that all quadrilaterals are totally separate from each other. A square and a rectangle are totally different. Right? square rectangle X

6
Let’s Review Core Lesson Compare and contrast a parallelogram and a rhombus. A parallelogram has: 2 sets of parallel sides 2 pairs of congruent sides A rhombus has: 2 sets of parallel sides 4 congruent sides parallelogramrhombus 2 sets of parallel sides 4 congruent sides AT LEAST 2 pairs of congruent sides

7
Let’s Review Core Lesson A square has: 2 sets of parallel sides 4 congruent sides 4 right angles A rhombus has: 2 sets of parallel sides 4 congruent sides square rhombus 2 sets of parallel sides 4 right angles 4 congruent sides How are a square and a rhombus similar and different?

8
Let’s Review Core Lesson How are a square and a rhombus similar and different? similardifferent They both have all congruent sides (4 equal sides). They both have 2 sets of parallel sides. A square must have 4 right angles.

9
In this lesson you have learned how to compare and contrast quadrilaterals by listing the attributes they share and those they don’t.

10
Let’s Review Guided Practice What makes a trapezoid different from a parallelogram? different A parallelogram MUST have 2 pairs of parallel sides, and a trapezoid has only 1. A parallelogram MUST have 2 pairs of congruent sides, and a trapezoid may or may not have any. parallelogram 2 sets of parallel sides 2 pairs of congruent sides trapezoid 1 set of parallel sides 1 pair of congruent sides (isosceles)

11
Let’s Review Extension Activities Choose two quadrilaterals for a classmate. Ask him/her to compare and contrast them for you. Have him/her tell you what makes them similar and what makes them different.

12
Let’s Review Extension Activities Make a list of all the quadrilaterals you know. Sort them into groups based on attributes they share. Be ready to explain why you chose to sort them the way you did.

13
Let’s Review Quick Quiz What attributes are shared between a square and a rectangle? How are a rectangle and a parallelogram similar and different?
