Question

Find the distance between Point P and Q.

Answer 1

Two circles each with radius 1 are tangent to one another. One line passes through the center of the first circle and is tangent to the second circle at the point P. A second line passes through the center of the first circle and is tangent to the first circle at the point Q. Find the distance between point P and Q.

Answer 2

What I though of so far

y^2 + x^2 = 1

Answer 3

Point D^2 = (x-x1)^2+(y-y1)^2

Answer 4

"Two circles each with radius 1 are tangent to one another. "
isn't it going to look like this:

Answer 5

hmm perhaps..probably

Answer 6

so, what now? It looks like a triangle...an equilateral one.
