Question

a student is trying to construct triangles using four different sets of angles. which set will form a triangle? 50, 50, 50 60, 80, 90 100, 45, 45 45, 65, 70 clear my selection

Explanation:

Step1: Sum of angles in a triangle

The sum of the interior angles of a triangle is \(180^{\circ}\).

Step2: Check each set

• For \(50,50,50\): \(50 + 50+50=150

eq180\)

• For \(60,80,90\): \(60 + 80+90 = 230

eq180\)

• For \(100,45,45\): \(100+45 + 45=190

eq180\)

• For \(45,65,70\): \(45+65 + 70=180\)

Answer:

\(45,65,70\)
