Explain why a square is a rectangle but a rectangle is not a square.
A square has all the properties of a rectangle: 2 pairs of equal and parallel sides, 4 right angles, etc.
The measure of one angle in a rhombus is 140 degrees, what is the size of the angle opposite to it? (Giving reason)
140 degrees because diagonally opposite angles in a rhombus are equal.
What is an ordered pair?
The x and y values as coordinates
Given the relation equation, 3x + 5 = y, find y when x = 5
20
3x - 4 < 20, find x
x < 8
