# Math Help - center of a chord

1. ## center of a chord

Hi,
i am little weak in maths. i need to find center of a chord. i have radius, and two end points of a chord. And say that center is at (x,y).i need to find the values of x,y. Please help me.

2. If you have the two endpoints in coordinate form you don't need the center of the circle to find the midpoint of the chord.

$x = \frac{x1 + x2}{2}$

$y = \frac{y1 + y2}{2}$
