Answer:
A. The triangles are not similar to each other.
Step-by-step explanation:
[] A triangle's angles all add up to 180°
-> For triangle ABC the angles are 80°, 40°, and unknown
-> For triangle DEF the angles are 80°, 70°, and unknown
[] For triangle ABC the angles are 80°, 40°, and unknown
-> 180° - 80° - 40° = 60°
-> Triangle ABC has angles of 80°, 40°, and 60°
[] For triangle DEF the angles are 80°, 70°, and unknown
-> 180° - 80° - 70° = 30°
-> Triangle DEF has angles of 80°, 70°, and 30°
[] A. The triangles are not similar to each other.
-> Since we do not have any side lengths, we must go off of AA (angle & angle) but as AA is not true, these triangles are not similar
