WebFigure 1 is a non-right triangle since none of its angles measure 90. We’ll start by deriving the Laws of Sines and Cosines so that we can study non-right triangles. The Law of Sines We’ll work through the derivation of the Law of Sines here in the Lecture Notes but you can also watch a video of the derivation: CLICK HERE to see a video showing
WebTo show that the angle sum of a triangle equals 180 degrees, draw a triangle, tear the angles and rearrange them into a straight line. Remember that the number of degrees in a straight line is 180 degrees. Do a similar activity to show that the angles of a quadrilateral add to 360 degrees.
