500
A triangle has angles that are all 60 degrees. What does this tell you about the triangle's sides? How would you classify this triangle?
What is the sides must also be equal. It is a regular triangle, or equilateral triangle.
500
A triangle has two sides of the same length. One of the angles measures 90 degrees. How would you classify this triangle by it's sides AND angles?
What is an isosceles right triangle?
500
A trapezoid has angles measuring 50, 50. Knowing that you need to know two angles, and knowing that a trapezoid has 360 degrees total, explain what the measure of the missing two angles must be.
What is 130 degrees each? If the two angles are both 50 degrees, then the other two angles must be equal as well. So, you could subtract 100 (50 + 50) from 360 and then divide that by the two angles you need. The answer you get is 130 degrees.
