In any triangle, the three angles inside always add up to 180 degrees.

Why Does This Happen?

1. Triangle Basics: A triangle has three sides and three angles.

2. Angle Relationships: If you draw a line that runs parallel to one side, it helps you see that the angles inside the triangle add up to 180 degrees.

Example

Let's look at a triangle with angles of 60 degrees, 70 degrees, and 50 degrees.

If we add them up: 60 + 70 + 50 = 180 degrees

This shows that the angles in a triangle always make the perfect total of 180 degrees!
