Use Pythagora's theorem in the right triangle CC'B (see figure at top) to write Let A 1 and A 2 be the areas of the triangle with lateral sides a1 = 2 and a2 = 10 respectively.Ī 1 = (1 / 2) a 1 2sin(?) and A 2 = (1 / 2) a 2 2 sin(?), corresponding angles are equal in similar triangles. Radius of inscribed circle to an isosceles triangle of base b = 10 and lateral side a = 12 is given by In triangle CDE we have: ?DCE + ?CDE + ?CED = 180° In trangle ABC: ?BCA + ?CAB + ?ABC = 180° Note that ?ABC, ?CBD and ?DBE make a straight angle. Solutions to the equation: b = 10 and b = - 6ī is a length and therefore is positive b = 10, h = b - 4 = 6Ī = √ (h 2 + (b/2) 2) = √ (36 + 25) = √61ĪBC is an isosceles triangle and therefore
