## First you have to use the Pythagorean theorem to find the lenght of c which is called the hypotenuse(that is the side opposite the right angle and is always the longest side of a right triangle)

c^{2} = a^{2} + b^{2}

c^{2} = 1^{2} + 1^{2}

c^{2} = 1 + 1

c^{2} = 2 ↔
c = √2

Based on what you learned from the writting the trig functions for the 30^{o}and 60^{o} angles write the 6 trig functions for a 45^{o} angle
