How to Make Your Flipbook: Take your 3 sheets of purple and 1 white paper and stagger them so that there is enough space between two sheets of paper for you to write something. About ¼ inch. Put the two colors that are the same on top.

Now, fold the top of your papers so that they overlap to make 4 more flaps. You want your top flap to be as big as you can make it to maximize the space you have on the back of it. Staple them at the top. You should now have a flipbook!

Trapezoids

Trapezoids Properties Properties Ways to Prove trapezoid: One pair of opposite parallel sides Ways to Prove isosceles trapezoid: Prove it is a trapezoid with congruent diagonals. . 1. At least one pair of parallel sides 2. Parallel sides are the bases 3. Base angles come in pairs and lie along each base. 4. Leg angles on same side are supplementary. Properties Trapezoids

PARALLELOGRAMS

Parallelograms ll. . . Theorems (Ways to Prove) Copy on the Parallelogram Flap Theorems (Ways to Prove) If both pairs of Opp. Sides are , then it’s a p’gram If both pairs of opp. s are , then it’s a p’gram If the diagonals bisect each other, then it’s a p’gram If both pairs of Opp. Sides are ll, then it’s a p’gram If one pair of opp. sides are  and ll, then it’s a p’gram Properties Opposite sides are Opposite angles are Consecutive angles are supplementary. The diagonals bisect each other. ll. . . Parallelograms

RECTANGLES

Rectangles Properties Theorems (Ways to Prove) Copy on the Rectangles Flap. Properties All properties of the parallelogram. The diagonals are . Four Right Angles Theorems (Ways to Prove) If it has 4 right angles, then it’s a rectangle. P’gram + the diagonals are , then it’s a rectangle. 3. P’gram + one right angle, then it’s a rectangle. Rectangles

RHOMBUSES

Rhombus Theorems (Ways to Prove) Properties If it has 4  sides, then it is a Rhombus. P’gram + diagonals are ┴, then it is a rhombus. P’gram + 2 consecutive congruent sides, then it is a rhombus. Properties All properties of a parallelogram. All sides are equal. Diagonals are ┴. Diagonal bisect opposite angles. Rhombus

SQUARES

Squares Properties Ways to Prove: A rectangle with 2 consecutive congruent sides. A rhombus with a right angle! Properties All the properties of a Rectangle, and a Rhombus 45o Squares

KITES

KITES Properties Ways to Prove: Def: A kite is a quadrilateral with two adjacent pairs of consecutive sides of the same length Ways to Prove: A quadrilateral with two adjacent pairs of consecutive sides of the same length A quadrilateral with perpendicular diagonals KITES

Polygon formulas to know: A regular polygon has all angles and sides that are equal in measure.
