Question

Which of the following could be the lengths of the sides of a 45°-45°-90° triangle?
A√3/2, √3/2, √2
B 3√2, 3√2, 6
C √3, 3, 2√3
D 3,4,5

Answer 1

D is obviously out, as is C, because a 45 45 90 triangle needs two identical sides. To choose between the other two, which set satisfies the Pythagorean theorem? a^2+b^2=c^2 (here a=b)

Answer 2

thank you! its B!

Answer 3

That's what I think, too, good job! :-)
