Properties of Rectangles
A rectangle has how many angles?
Four angles
True or false: The formula of an area is length x height
True
How is a rectangle different from a square?
Squares have 4 equal sides while rectangles have opposite equal sides.
To find the height of a rectangle, all we need is the area of the rectangle and nothing else.
False. We need to length too.
are opposite sides of a rectangle parallel or perpendicular?
Parallel. Always the same but they never meet. How sad!
If you only have the area and one length of a rectangle, can you find the other length of the rectangle? How?
Yes. The length of a rectangle is parallel to each other so if we have one length, the other is the same.
True or false: The length of a rectangle and the height of a rectangle are perpendicular to each other.
True
True or False: A rectangle has 4 right angles, just like the square
True. Both squares and rectangles have 4 right angles.
What is the fancier, more mathematical way to say 'points' of a shape?
Vertices (Vertex singular)
4 right angles. 4 x 90 degrees =360 degrees
