Answer:
5a) 2 sides are equal to each other
5b)

6) 16

Explanation:
5b) I'm assuming that in this question you are trying to find the hypotenuse? So you use the pythagorean theorum, which is a^2+b^2=c^2. c represents the hypotenuse, so it would be 10^2+10^2=c^2 because the two sides are equal. Then 100+100=200 and the square root of that is 10\sqrt{2}.
6)a^2+b^2=32^2
since a=b you can write the equation as, 2a^2=1024
a^2=1024/2 , which equals a=\sqrt{512}
and simplify it to 16
