I use this with my advanced class and they LOVED the challenge and were asking me if I had any more triangles for them to work on.
This could also used in a Math Centers format.
Students work to find multiple missing angles in each problem.
This file includes:
-5 different challenges
-answer keys for each challenge
Prior Knowledge Needed:
-sum of 3 triangle angles = 180 degrees
-right angles = 90 degrees
-isosceles triangles have two congruent sides and angles
**This should not be used as an exercise of measuring angles with a protractor.
