• Find missing side of triangle using trig calculator. The opposite side is given to us: 2, but the hypotenuse is not. Since we have a right-angled triangle, we can use Pythagoras to find the hypotenuse. If the hypotenuse is c, then a and b are both 2, so the equation a^2+b^2=c^2 becomes: c^2=2^2+2^2=4+4=8 . Square rooting both sides, we get: c=\sqrt{8}=2\sqrt{2}Trigonometry helps us find angles and distances, and is used a lot in science, engineering, video games, and more! Right-Angled Triangle.
