Question 241181: Hello.
I am doing a geometry problem and I have to find the measure of the sides and classify each triangle by its side.
But.. one of the coordinates/points are a radical . for example.
A(0,5) B(5 radical 3,2)
How can I solve this problem with the radical in it ?
Thank You

Question 238420: An obelisk is a tall, thin, four-sided monument that tapers to a pyramidal top.
The most well-known obelisk to Americans is the Washington Monument on
the National Mall in Washington, D.C. Each face of the pyramidal top of the
Washington Monument is an isosceles triangle. The height of each triangle is
55.5 feet, and the base of each triangle measures 34.4 feet. Find the length,
to the nearest tenth of a foot, of one of the two equal legs of the triangle.

I'm not sure how you calculate the length of a leg when they give you the length of the base, and the height of the triangle. I'm sure it's in the back of my head somewhere. I just need help getting it out of there and onto the paper.
Do I use the Pythagorean Theorem?
Like, a+b=c but with the squares in position?

THANKS! (:
