Proportional & Non-proportional & Similarity

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio, meaning as one quantity increases or decreases, the other does so in a consistent manner.

Front

What is the definition of non-proportional relationships?

Back

Non-proportional relationships do not maintain a constant ratio; as one quantity changes, the other does not change in a consistent way.

What is a characteristic of a graph that represents a non-proportional relationship?

Back

A graph of a non-proportional relationship is not a straight line or does not pass through the origin.

In similar figures, how are the side lengths related?

Back

The side lengths of similar figures are proportional.

Front

If the sides of two triangles are in the ratio 2:3, what can we say about the triangles?
