ΔUTS and ΔUDE are similar because the angle-angle theorem is satisfied.
What is the triangle?
Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
Chaim tried to prove that ΔUTS ≈ ΔUDE in the following figure.
A. First, ∠SUT and ∠EUD are equal because they both are vertically opposite angles.
∠SUT = ∠EUD
B. It can be observed that the sides ST and DE of the triangle are parallel to each other.
C. ∠UST and ∠UED Alternate interior angles formed by parallel lines are congruent.
D. ΔUTS and ΔUDE are similar because the angle-angle theorem is satisfied.
