How to Use IS KNOWN AS and ARE KNOWN AS to Find the meanings of Words!


A shape made of three straight lines is known as a triangle. There are different kinds of triangles. Some triangles are bigger than others. Some triangles have different shapes than others. Triangles that are the same shape and size are known as congruent triangles. If they are the same shape, but are different sizes, they are called similar triangles.


The context clues such as, is/are called, and is/are known as work differently from the other context clues we have looked at. The words we want to know the meaning of are found AFTER these context clues. The meanings of the words are found IN FRONT OF the context clues.
