Triangles in Geometry (Definition, Shape, Types, Properties
WebSolution: We 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°.
