In triangle A B C , A B = 4,680   millimeters   mm and B C = 4,680  

Question

In triangle A B C , A B = 4,680 &#160; millimeters &#160; mm and B C = 4,680 &#160; mm . Which statement is sufficient to prove that triangle A B C is equilateral?

Accepted Answer

Choice A is correct. In an equilateral triangle, all three sides have the same length. It&rsquo;s given that in triangle A B C , A B = 4,680 &#160; mm and B C = 4,680 &#160; mm . Therefore, if A C = 4,680 &#160; mm , then all three sides of triangle A B C have the same length, so triangle A B C is equilateral. Therefore, A C = 4,680 &#160; mm is sufficient to prove that triangle A B C is equilateral. Choice B is incorrect and may result from conceptual or calculation errors. Choice C is incorrect and may result from conceptual or calculation errors. Choice D is incorrect and may result from conceptual or calculation errors.
