## INTRODUCTION TO QUADRILATERALS...

## RECTANGLES AND RHOMBUSES AND SQUARES, OH MY!

## Rectangle A rectangle has four right angles. | ## Rhombus A rhombus has congruent opposite sides; it's a sideways diamond :)) | ## Square A square has four congruent sides and four right angles. |

## a real-life rectangle... ..it's pretty self-explanatory. | ## a real-life rhombus... There is a yellow rhombus inside the Brazilian Flag. | ## a real-life square... There are multiple squares inside a single waffle. |

## another real-life rectangle... an ice-cream sandwich | ## another real-life rhombus... There are rhombuses inside of a net used in various sports. | ## another real-life square... Cheez-It crackers are squares. |

## RHOMBUS EXAMPLE PROBLEM

## WHAT ARE THE PROPERTIES OF PARALLELOGRAMS?

Therefore, rectangle + rhombus = square

## a rectangle has four right angles... | ## a rhombus has four congruent sides... | ## and a square has four congruent sides and four right angles rectangle + rhombus = square parallelograms are related! |

## TRAPEZOID VS ISOSCELES TRAPEZOID

## TRAPEZOID

## ISOSCELES TRAPEZOID

## TRAPEZOID GIFT BOXES!!! these little gift boxes have one pair of congruent sides, the left side and the right side. | ## ISOSCELES TRAPEZOID This popcorn box is an isosceles trapezoid because it has a pair of congruent legs. |

## TRAPEZOID EXAMPLE PROBLEM

## KITES

## Example of a...kite This is also pretty self-explanatory. A kite is, well, a kite. It has two pairs of consecutive congruent sides, but no congruent opposite sides because each side goes out a direction opposite of its opposite side. | ## Another example of a kite These earrings are a kite. |

## KITE EXAMPLE PROBLEM
