By the end of this video, students will be able to determine the difference between four types of angles (straight, right, obtuse, acute).
A straight angle measures 180 degrees.
A right angle measures 90 degrees and is like the corner of your paper.
An acute angle measures less than 90 degrees, but more than 0 degrees.
An obtuse angle measures more than 90 degrees, but less than 180 degrees.
