If AB = BC in traingle ABC, then which of the following must be true?
2 answers:
Answer: m∠A = m∠C
Step-by-step explanation:
If AB = BC in triangle ABC, then Δ ABC is a isosceles triangle.
We know that there is a theorem which says that "Angles opposite to equal sides of a triangle are equal".
Thus if AB = BC, then
m∠A = m∠C [Angles opposite to equal sides of a triangle are equal]
Thus, option 2 is right. If AB = BC in triangle ABC, then m∠A = m∠C must be true.
Number one should be the right answer.
