Geometry Help!

Answer 1

for the side opposite of the 8 value, it would be the same. for x, try getting the answers in the same format

Answer 2

so those two would be 8 but I'm still unsure of how to find x. could you please help me?

Answer 5

I noticed right away that this is an isosceles right triangle. What does that tell you about the lengths of the two legs of this right triangle?

Answer 6

Right so like I said that last time

Side ratios of this isosceles triangle are



so that means

Answer 7

So if that side you have is 8...we know that both are 8

Answer 8

so the last part would be 8sqrt2?

Answer 9

correct

Answer 10

is it always like that for the isosceles triangle?

Answer 11

This approach, using ratios, is just fine!

An alternative approach would be to use the Pyth. Theorem to find the hypotenuse, x.

Thanks for your contributions, johnweldon.
