Drawing right, acute, and obtuse angles

The first instance of  is under the 4th Grade Math Mission. This exercise practices making angles and recognizing how to classify angles by size compared to a right angle.

Types of Problems
There are two types of problems in this exercise:


 * 1) Draw a type of angle (one option): This problem has the student draw an angle of a certain type using three points. They are also expected to tell why the angle is this type by comparing to 90 degrees.DA1.png
 * 2) Draw a type of angle (multi-option): This problem has the student draw an angle of a certain type but they need to follow the directions given expressly. They are also expected to tell why the angle is this certain type by comparing it to 90 degrees.DA2.png

Strategies
This exercise is easy to get accuracy badges and the interface for drawing angles is fairly easy to use. It is medium difficulty to attain speed badges because moving things around is not fast to do.


 * 1) On problem type one the answer always seems to be a 90 degree or right angle. This does not necessarily have to be the case so it is easy to imagine new problems of the type eventually being developed or extended.
 * 2) On the second type of problem start with vertex at A, move one side through B, then finish the problem.
