Triangle Angle Validation: Do 60°, 50°, and 70° Form a Valid Triangle?

Question

Three angles measure as follows: 60°, 50°, and 70°.

Is it possible that these are angles in a triangle?

Video Solution

Solution Steps

00:00 Determine whether the following angles can form a triangle
00:03 The sum of angles in a triangle equals 180
00:07 Substitute in the relevant values according to the given data and proceed to solve
00:11 The sum of angles equals 180, therefore they could form a triangle
00:14 This is the solution

Step-by-Step Solution

Recall that the sum of angles in a triangle equals 180 degrees.

Let's add the three angles to see if their sum equals 180:

60+50+70=180 60+50+70=180

Therefore, it is possible that these are the values of angles in some triangle.

Answer

Possible.
