300
Tell whether the angle measures are those of a triangle. If so, classify the triangle using angles.
25 degrees, 70 degrees, 85 degrees
Yes it is a triangle because the angles add up to 180 degrees. It is an acute triangle.

Challenge -- Use Diagram #6 to answer the following.
Use what you know about triangles an dangles to find the measurea of the missing numbered angles.
What is <5 = 22 degrees
<6 = 90 degrees
< 4 and <2 = 68 degrees

Challenge: A regular pentagon has how many sides and what are the angle measurements?
What is 5 sides and each angle measures 108 degrees.

Use Diagram #10 to answer. Classify the polygon and tell whether it is regular. Explain.
The polygon is a pentagon, however it is not regular because the ANGLES are not all equal. (Yes, the sides are, but not the angles.)
