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°. WebJan 13, 2024 · The angle sum of a triangle will always be equal to 180 °. The angle sum of a quadrilateral is equal to 360 °, and a triangle can be created by slicing a quadrilateral in half from corner to corner. Since a triangle is essentially half of a quadrilateral, its angle measures should be half as well. Half of 360 ° is 180 °.

WebJan 7, 2013 · One other interesting aspect of circles is that every circle can be divided into 360 units called degrees. So, if you turn around in a full circle, you turn 360 degrees. If you simply turn halfway around — a half-circle — you turn 180 degrees. So why 360 degrees instead of something simpler, like 100 degrees? WebHow many degrees are all the angles in a triangle? 1)If you know the measure of sides,you can check whether it is a 30–60–90 triangle,45–45–90 triangle or 37–53–90... 2)Use of … how he loves by john mark mcmillan
