Best ResponseYou've already chosen the best response.2Okay, you have an isosceles right triangle here, because both of the angles are the same. What does that imply about the associated sides?

Best ResponseYou've already chosen the best response.0They have 2 equal sides and 2 equal angles?

Best ResponseYou've already chosen the best response.2Right. So what is the length of the other leg of the triangle?

Best ResponseYou've already chosen the best response.2come on, we said this was an isosceles triangle, which means two equal angles and two equal sides!

Best ResponseYou've already chosen the best response.2Doesn't that mean ??? has to be 8?

Best ResponseYou've already chosen the best response.0why would it be 8 ?

Best ResponseYou've already chosen the best response.2because it is an isosceles triangle. One of the sides is 8. Another one must be 8 as well, and it can't be the hypotenuse, because the hypotenuse is the longest side.

Best ResponseYou've already chosen the best response.2it's an isosceles triangle because it has two equal angles. You see that part, right?

Best ResponseYou've already chosen the best response.2So we can update our drawing: dw:1393635393884:dw If the two sides labeled 8 are \(a=8,b=8\) respectively, what is the length of the hypotenuse, \(c\)? Use the Pythagorean theorem

Best ResponseYou've already chosen the best response.0its a^2+b^2=c^2 do I add the 45 degrees together to get c? or is the 8?

Best ResponseYou've already chosen the best response.2The Pythagorean theorem relates only to the lengths of the sides. Angles don't matter (except, of course, that one of them must be 90 degrees for it to be a right triangle).

Best ResponseYou've already chosen the best response.2\[a^2+b^2=c^2\]\[8^2+8^2=c^2\]\[2*8^2 = c^2\]Take the square root of both sides:\[\sqrt{2*8^2} = \sqrt{c^2}\]Simplify\[8\sqrt{2} = c\] If you have a \(45^\circ/45^\circ/90^\circ\) triangle such as this one, the side lengths are always in the ratio \(1:1:\sqrt{2}\)

Best ResponseYou've already chosen the best response.0is that the way you would do it for this kind of triangle too ?

Best ResponseYou've already chosen the best response.0Use the Pythagorean theorem

Best ResponseYou've already chosen the best response.2Well, yes, if you know 2 sides in a right triangle, you can use the PT to find the 3rd side.
