Question

Every student from the group should do this activity. Draw a circle in your notebook. Draw a chord of the circle. Join the midpoint of the chord and centre of the circle. Measure the angles made by the segment with the chord. Discuss about the measures of the angles with your friends. Which property do the observations suggest?

Answer 1

The meausure of the angles made by the drawn segment with the chord is 90°. 

Thus, we can conclude that, the segment joining the centre of a circle and the midpoint of its chord is perpendicular to the chord.
