Given a circle (O) and its diameter AB. C is a point on the circle which is different from A and B. H is the projection of C on AB. I is the midpoint of CH. The line passes through I and perpendiculars with OC cut (O) at 2 points D and E. Prove that \(\Delta CDH\)is an isosceles triangle.
On the number line, point A has coordinate -6 and point B has coordinate 6.
Suppose that pointC is the midpoint of A,B then C's coordinate is ...
