Open a new "GeoGebra" window. 2. Draw a circle. 3. Draw two chords of equal size to the circle. 4. Draw perpendicular lines from the centre to the chords. 5. Mark points of intersection. 6. Measure the perpendicular distances. 7. What do you observe? Assignment 2 1. Verify if point "C" is the midpoint of segment "f(AB)"? Assignment 3 1. Open a new "GeoGebra" window. 2. Draw a circle. 3. Draw tangents from an external point. 4. Mark points of intersection of the tangents. 5. Join the centre of the circle to intersection points 6. Measure angle at the centre and measure angle between the tangents. 7. What is the sum of the two angles? 8. Join the centre and the external point. 9. Does the line-segment bisect the angle at the centre?
