Web15 jun. 2024 · List the sides in order, from shortest to longest. Figure 4.25.8 Solution First, find m\angle A. From the Triangle Sum Theorem: m∠A + 86 ∘ + 27 ∘ = 180 ∘ m∠A = 67 ∘ 86 ∘ is the largest angle, so AC is the longest side. The next angle is 67 ∘, so BC would be the next longest side. 27 ∘ is the smallest angle, so AB is the shortest side. WebIf a triangle has sides a,b,c then all of the following conditions must be true a b+c b a+c c a+b Any two sides must add to be larger than the third side. See the triangle inequality theorem. In option 1, we have: a = 4, b = 4, c = 8 And a+b = 4+4 = 8 which does not exceed c = 8 In other words, c a+b is not true. A triangle isn't possible here.
