Since each of the six interior angles in a regular hexagon … WebMar 3, 2024 · A polygon has the same number of interior angles as sides. For example, a triangle always has 3 angles, while a square or rectangle always has 4, and so on. Next, use the formula (n – 2) x 180 to find the total number of degrees of all the interior angles combined. In this formula, n is equal to the number of interior angles.
WebThe measure of this angle is x. This one's y. This one is z. And what I want to prove is that the sum of the measures of the interior angles of a triangle, that x plus y plus z is equal to 180 degrees. And the way that I'm going to do it is using our knowledge of parallel lines, or transversals of parallel lines, and corresponding angles.
