In ΔABC, ∠A = 40° and ∠B = 60°. The longest side is
AC
BC
AB
CD
By angle sum property, ∠C = 80°, in a triangle the greater angle has the longer side opposite it.
In ΔABC, ∠A=40∘ and ∠B=60∘. Then, the longest side of ΔABC is(a) BC (b) AC(c) AB (d) cannot be determined
In an isosceles ΔABC, ∠A is 30∘. The sides AB and AC are equal. Using constructions, find which side of ΔABC is the shortest.
