The Interior Angles of a Triangle add up to 180°. Let's try a triangle: 90° + 60° + 30° = 180°. It works for this triangle. Now tilt a line by 10°: 80° + 70° + 30° = 180°. It still works! One angle went up by 10°, and the other went down by 10°.

14 cze 2023 · The formula for determining one interior angle in a regular polygon is given below: One interior angle = (n-2) x 180°/n, here n = total number of sides. Let us take an example to understand the concept better, For an equilateral triangle, n = 3. Thus, One interior angle = (n-2) x 180°/n, here n = 3 = (3-2) x 180°/3 = 60°
