Translation – A term used in geometry. Often called a slide. The figure or shape is moved from each point of the figure/shape in the same direction and distance.

Variable – When a letter is used to represent a number or number in equations and or expressions. E.g., in 3x + y, both y and x are the variables.

Venn Diagram – A Venn diagram is often two circles (can be other shapes) that overlap. The overlapping part usually contains information that is pertinent to the labels on both sides of the Venn diagram. For instance: one circle could be labeled ‘Odd Numbers’, the other circle could be labeled ‘Two Digit Numbers’ the overlapping portion must contain numbers that are odd and have two digits british __pound to usd__ history. Thus, the overlapping portions shows the relationship between the sets. ( Can be more than 2 circles.)
