Move Points A and C and see the relationship between a, b and c.
Notice that the ratio a:b:c always remains at 1:1: √2. If a right angle triangle is isosceles, then the angles will be, 45° , 45° and 90°. We will call this the 45-45-90 triangle. If the sides of this triangle is 1 then the hypothenuse will be: c^2 = a^2 + b^2 => c^2 = 1*1+ 1*1 c^2 = 1 + 1 => c^2 = 2 => c = √2 [b]≃ 1.41[/b]
