My parallelogram story

My Parallelogram Story: Rectangle

By: Melissa Perez

Me! My name is Melissa. I’m 14 years old and in the

ninth grade. I’m the only girl. I love pink! I take geometry with one of my favorite teachers, Ms.Bush. She an amazing teacher.

Properties Of A Parallelogram

Opposite sides are parallel

Opposite side are congruent

One pair of sides are parallel and congruent

Opposite angels are congruent

Diagonals bisect each other

RectangleAll four angels are right angels

Diagonals are congruent

Comparison A rectangle and square both are parallelogram.

They both have four right angels.

A rectangle and a rhombus have nothing in common expect that they are both parallelogram .A rhombus has all congruent a rectangles doesn’t

Contrast A rhombus has four congruent sides a rectangle

doesn’t. A rectangle has opposite sides congruent.

A square has four right angels and all congruent sides. A rectangle doesn’t have congruent.

Venn diagram

Rectangle Rhombus

• Diagonals are congruent

• Diagonals are congruent

• 4 congruent sides

• Diagonals bisect angels

• Diagonals are perpendicular

Parallelogram

mAT= ZeromRS= Zero mAR= Undefined mTS= Undefined

Coordinate Proof Question

JustificationIn the last slide to prove that quadrilateral ATSR

was a rectangle I found the slopes of the opposite sides. By finding the opposite sides I checking to see if the angles were perpendicular. If the slopes were negative reciprocal then the angels are perpendicular. AT and RS both equaled zero. AR and ST both equaled undefined. The slopes were negative reciprocal therefore it is a rectangle.

Conclusion In conclusion I learned that a square has the

qualities of a rhombus and rectangle but a rhombus and rectangle doesn’t have the qualities of a square. I don’t really like the Photo Story because it repetitive and boring.
