WebSubstituting angles A and B into our previous equation, ∠A + ∠B + ∠BCA = 180°, where ∠BCA = ∠C. Exterior angles. For a triangle, an exterior angle is an angle formed by one side of the triangle and a line extended from another of its sides. The measure of an exterior angle of a triangle equals the sum of its two remote interior angles. WebFinally, the sum of interior angles is found with the formula 180 (n-2) where n is the number of angles. since it tells us the sum we can find the number of angles. 180 (n-2)=540 n-2 = 3 n = 5 So five corners, which means a …

WebOct 13, 2024 · Angles in an isosceles triangle add to 180°. We subtract the 140° from 180° to see what the size of the remaining angle is. 180° – 140° = 40° The missing angle on the top of this isosceles triangle is 40°. We can also think, “What angle do we need to add to 70° and 70° to make 180°?” The answer is 40°.
