Triangle ABC = Triangle EDF. AB = 8cm, angle F = 70 degrees. Find ED and angle C.

1) Determine the length of the side ED, if we are told by the condition that the triangle ABC = triangle EDF, and the length of the side AB = 8 cm, then we can safely say that the side ED = AB. We get:

AB = ED = 8 cm.

2) Determine the degree measure of the angle C, if it is also known that the triangle EDF = ABC, and the angle F = 70 °, then the angle C is also = 70 °. We get:

∠F = ∠C = 70 °.

Answer: side length AB = ED = 8cm, and ∠F = ∠C = 70 °.
