Answer:
A.) Measurement of angle 1 is 60, and measurement of angle 2 is 60.
Explanation:
We know because those are both acute angles, and cannot be 135, so that eliminates that option. We also know that 45 + 67.5 wont work because the last angle would need to measure 67.5 which would not make sense based on the fact all of the triangles are equal in size and angle measurement. The last option is wrong because 22.5 is way to small for there to only be 8 triangles in the octagon. All the angle measures have to be equal in order for this model to work.
