WebA triangle is a three-sided polygon that has 3 angles, and 3 vertices. Learn the definition of triangles, their types, parts, properties using a variety of examples. A triangle is a three-sided polygon that has 3 angles, and 3 vertices. WebAll three angles in any triangle always add up to 180 degrees. So if you only have two of the angles with you, just add them together, and then subtract the sum from 180. A Triangle has three angles A, B, and C. Angle A …
WebThe polygon has three sides so we are looking at a triangle. 2 Determine the size of the angles/side lengths within the polygon. Angles in a triangle total 180^ {\circ} 180∘ and so the missing angle is equal to 180 - (70+55)=55^ {\circ} 180 − (70 + 55) = 55∘. 3 Recognise the other properties of the polygon. Web3) The formula for the sum of the interior angles of any polygon is (n-2) * 180, where n equals the number of sides. For example, for a triangle you would have (3-2) * 180 = 180.
