Let *a* and *b* lines support two perpendicular diameters of a circle of center O and radius 3 cm. *M* be a point on the circle and *M'* and *M"* feet perpendiculars taken from M *a* and *b*. Find out segment's length *M'M"*.

Here it is simple to notice that the OM'MM" is a rectangle.

And the diagonals in rectangle have the same length, So though, we have

M'M" = OM = r = 3cm
