Rules for sides of triangles
WebbMultiply both sides by AC: sin (x)AC DC = sin (180−y) 1 Divide both sides by sin (x): AC DC = sin (180−y) sin (x) But sin (180−y) = sin (y): AC DC = sin (y) sin (x) Both AB BD and AC DC are equal to sin (y) sin (x), so: AB BD = AC … WebbArea = √ (s (s-a) (s-b) (s-c)) Where s is the semi-perimeter of the triangle, which is the sum of the three side lengths divided by 2, and a, b, and c are the lengths of the three sides of …
