Web13 jun. 2024 · To work out the size of angles b and c, we will first find the sum of the three angles above. 100° + 120 ° + 120° = 340°. We can subtract this from 540° to get 200°. This means that angles b and c must add together to make 200°. Since they are both the same size, we will just divide 200° by 2. Angle b = 100° and angle c = 100°.

Web1. The angles always add to 180°: A + B + C = 180°. When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c. WebAn intuitive way to show this is to cut out a triangle from paper. Rip off the corners and put them together with the points of the triangle touching. If you make them all adjacent to one another, they will form 180 degrees. To prove this, let's say we have a triangle ABC. We could create a line parallel to BC through point A.
