It is important to learn how to write about math ideas.
Let's use what we know about the measure of straight angles to write a description of a straight angle. 

        Ex. A straight angle is an angle that measures 180


The first part of the description will tell
the larger group the word belongs to
In this case, a straight angle belongs to the larger group of "angle".

 

Ex. A straight angle is an angle.

 


The second part of the description will tell what makes this angle different
from other angles in the group.

Ex. A straight angle is an angle that measures 180
