Use the Triangle Sum Theorem and Exterior Angle Theorem as needed. Classify triangles using both the side and angle systems where asked.
- 1.A triangle has angles 44 degrees and 61 degrees. Find the third angle.
- 2.Classify a triangle with sides 7, 9, 9 by its sides.
- 3.An exterior angle of a triangle measures 132 degrees. One remote interior angle is 58 degrees. Find the other remote interior angle.
- 4.A triangle has angles 30 degrees, 60 degrees, and 90 degrees. Classify it by angle type.
- 5.A student claims a triangle can have angles 100 degrees, 90 degrees, and -10 degrees because they still add to 180. Explain what is wrong.
