The total interior angles of a triangle = 180°
The triangle scored three treble twenties in her darts game which gave a combined score of 180.
The total internal angles of a triangle = 180°
Example 1
`60°+90°+30°=180°`
The interior angles of a triangle add up to 180°
Example 2
All we have done in this example is push the one side (A-B) of the triangle further in.
`100°+50°+30°=180°`
Example 3
An equilateral triangle will have 3 equal internal angles and would be
`180^circ/3=60^circ`
Each internal angle is 60°.

But the interior angles would still add up to 180°.
