WebNo matter how you position the three sides of the triangle, the total degrees of all interior angles (the three angles inside the triangle) is always 180°. This property of a triangle's interior angles is simply a specific example … WebWe know that the sum of the angles of a triangle adds up to 180°. Therefore, the unknown angle can be calculated using the formula Sum of interior angles of a triangle = Angle 1 + Angle 2 + Angle 3 ⇒ 180° = 45° + 63° + Angle 3 ⇒ Angle 3 = 180° - (45° + 63°) Angle 3 ⇒ 72° ∴ The third angle is 72°. Web540°. At the very end of this set of flashcards, I'll give you the sum of all the angles of all the polygons so you don't have to memorize all of those numbers.
