INTRODUCTION TO QUADRILATERALS...
RECTANGLES AND RHOMBUSES AND SQUARES, OH MY!
A rectangle has four right angles.
A rhombus has congruent opposite sides; it's a sideways diamond :))
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 GIFT BOXES!!!
these little gift boxes have one pair of congruent sides, the left side and the right side.
This popcorn box is an isosceles trapezoid because it has a pair of congruent legs.
TRAPEZOID EXAMPLE PROBLEM
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.
