Use 90 degrees and the terms less than, greater than, or equal to to describe acute, obtuse, and right angles.

Obtuse angles are greater than right angles, or 90 degrees. Acute angles are less than right angles, or 90 degrees. Right angles are equal to 90 degrees.

What is a protractor? How do you line up a protractor on an angle? 

Protractors are the tool used to measure angles. You must line the protractor up on the vertex of an angle and it must go through 0.

Draw a right, scalene triangle. Draw all possible lines of symmetry. Describe what makes it a right triangle and what makes it a scalene triangle.
A right triangle has one right angle in it and a scalene triangle has all unequal sides. With scalene triangles there are no lines of symmetry.
500
A right angle has a line segment cutting through it dividing it into two parts. One part measures 24 degrees. What does the other part measure? What equation would you use to represent this problem?
90-24=X, X= 66 degrees
