Two points, A and B are on a circle, with point O being the center. The lin segment connecting A and B is equal to 2, and the perpendicular distance from the line segment AB to the center is equal to 1. What is the radius of the circle?

3. The attempt at a solution

I think i might have this one, I can draw it out and it seems to work, but im not positive why.

So I have the perpendicular being 1, and since its a circle, it seems to me that on each side of that perpendicular point, the two parts will be equal. Now I have a right triangle, sides of 1, 1, and then the hypotenuse. So 1 squared plus 1 squared is equal to 2... to get the hypotenuse, in this case, the radius, it would be the squareroot of 2. Correct?
