Finding hypotenuse in a 45-45-90 triangle.
1 Answer | add yours
The hypotenuse of a right angle triangle can be evaluated using Pythagora's theorem, such that:
`a^2 = b^2 + c^2`
`a` represents the hypotenuse
`b,c` represent the legs of triangle
A `45^o-45^o-90^o` triangle is an isosceles right angle triangle, whose legs are equal in length, such that:
`b = c => b^2 = c^2`
`a^2 = 2b^2 => a = bsqrt 2`
Hence, evaluating the hypotenuse of an isosceles right angle triangle, yields `a = bsqrt 2.`
