For A(x1,y1)A(x_1,y_1)A(x1,y1) and B(x2,y2)B(x_2,y_2)B(x2,y2), the distance is [...]\text{[...]}[...].
A
For A(x1,y1)A(x_1,y_1)A(x1,y1) and B(x2,y2)B(x_2,y_2)B(x2,y2), the distance is (x2−x1)2+(y2−y1)2\boxed{\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}}(x2−x1)2+(y2−y1)2.
B
They intersect at two distinct points.
C
It bisects the chord.
D
They touch externally, since 10=4+610=4+610=4+6.
