One fact I know about rectangles is that opposite sides are equal in
length.

The perimeter is 3 inches + 3 inches + 5 inches + 5 inches =
16 inches
I hope you said “inches” and not “centimeters”!!!!!!!!

The perimeter of this square is2cm + 2cm + 2cm + 2cm = 8cm
You could also write 4 X 2 cm = 8 cm

The Perpendicular Song(to the tune of “Yankee Doodle Dandy”)
Two lines are perpendicular if they form a right angle.
“Right angle” is another way that you can say “square corner”.
These lines are perpendicular: These lines aren’t:These lines are perpendicular: These lines aren’t!
![Page 33: Unit 2 Super Review Geometry Guy. A POINT identifies a location in space. Draw: Write: Say:](https://reader035.vdocuments.net/reader035/viewer/2022070403/56649f2a5503460f94c4435f/html5/thumbnails/33.jpg)
Do you see the square corners?(also known as “right angles”)?
Important: When we say “right angles”, we don’t mean they “go to the right”, or that any other kind of angle is “wrong”!!!
Two lines are perpendicular if they form a right angle.
“Right angle” is another way that you can say “square corner”.

Now, let’s sing The Parallel Song!
SORRY! There is no Parallel Song!

Parallel lines• are the same distance apart
everywhere
• will never intersect in either direction

A parallelogram is…
a four-sided figure…
whose opposite sides are…
parallel!
Do you see how the OPPOSITE SIDES of these QUADRILATERALS are parallel to each other? These figures are PARALLELOGRAMS!

A rhombus is a parallelogram with 4 equal sides.
A square is a special rhombus because it has 4 right angles.
And, like we said before,
A square is a special rectangle because it has 4 equal sides.

Now, the final goodbye from Geometry Guy!
You’re
ALL
special!
I told you I was special!
