Formula for Hypotenuse of an Isosceles Right TriangleLet’s assume an Isosceles Right Triangle Here, equal sides are a And, hypotenuse is c We need to find relation between a & c Making a square, and then double of a square in our figure Now, Area of square REST = 2 × Area of Square PEAR Area of square with side c = 2 × Area of square with side c c × c = 2 × a × a 𝐜^𝟐=𝟐𝒂^𝟐 Now, we can use this formula to find either c or a Let’s do some questions
