Angle types

The first instance of  is under the 4th Grade Math Mission. This exercise has a protractor which a student can use to understand different angle types.

Types of Problems
There is one type of problem in this exercise:


 * 1) Use the protractor to classify the angle: On this problem an angle is drawn and the student can use the protractor to measure the angle. After doing so, they choose whether the angle is acute, right or obtuse.AT1.png

Strategies
This exercise is very easy to get accuracy and speed badges.


 * 1) There is no need to use the protractor unless you want to. Therefore you can visually inspect (or use a piece of paper) and determine quickly how the angle compares to a right angle.
 * 2) Right angles are labeled with a box measuring the angle (standard notation).
