Given a circle of radius 5cm and centre O. OM is drawn perpendicular to the chord XY. If OM = 3cm, then length of chordXY is
Question
Solution 1
To solve this problem, we will use the Pythagorean theorem.
-
First, we know that OM is perpendicular to the chord XY, which means that OM is a radius of the circle that bisects the chord XY. Let's call the point where OM intersects XY as point N. So, we have a right triangle OMN.
