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.
Real Life Examples
My Beat’s box
My iPod
My Marilyn Monroe photo
My Mom’s iPad mini
On my door
My Moms Mac
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.
