All right. You do observe that this is a 454590 which has a leg 16 right?

Okay. Another thing that I should tell you—if two angles are equal, then two sides are equal too! Do you know what a triangle with two equal sides is known as?

Right triangle?

There are names given to the triangles based on their *sides*. Equilateral triangle  all sides equal. Isosceles triangle  two sides equal. Scalene triangle  no sides equal.

oh lol xD okay so it's isosceles sorry D:

All right, so an isosceles triangle has 2 angles and 2 sides equal. So, we have TWO angles equal. This must be an isosceles triangle(which makes the two legs equal by default).

Yes! You got it! Now can you use the Pythagorean Theorem? :)

16^2 + 16^2 = c^2? C in this case being RT?

It asks for the radical form :P

___ √512 ? maybe?

Yep, but you have to simplify that radical.

Yay! As you are done with the long method now, I'd give you a shortcut to do such questions involving a 454590 triangle!

Okay :D

If you are given a leg of a 454590 triangle, you just put \(\sqrt2\) in front of it to get the hypotenuse ^_^ • If the leg is \(8\), then the hypotenuse is \(8\sqrt2\) • If the leg is \(1281283283283249483483\), then the hypotenuse is \(1281283283283249483483 \sqrt2\)

D: That is genius

And, for example, if the hypotenuse is \(\pi\sqrt2\), then the leg is \(\pi\). Remember, you just remove that \(\sqrt2\) in the case of \(hypotenuse \Longrightarrow leg \).

But remember, this method is \(\textbf{only for the 454590 triangles}\).
