Draw any line segment `bar(AB)`. Mark any point M on it. Through M, draw a perpendicular to `bar(AB)`. (use and compasses)

Draw a line / and a point X on it. Through X, draw a line segment bar(XY) perpendicular to l. Now draw a perpendicular to bar(XY) at Y. (use ruler and compasses)

Let I be a line and P be a point not on I. Through P, draw a line m parallel to I. Now join P to any point Q on I. Choose any other point R on m. Through R, draw a line parllel to PQ. Let this meet I at S. What shape do the two sets of parallel lines enclose?

Draw a circle with centre C and radius 3.4 cm. Draw any chord AB. Construct the perpendicular bisector of bar(AB) and examine if it passes throught C.

Draw a circle with centre C and radius 3.4 cm. Draw any chord bar(AB) . Construct the perpendicular bisector of bar(AB) and examine if it passes through C. Repeat Queston 6, bar(AB) happens to be a diameter.

In a circle with centre 'O' . bar(AB) is a chord and 'M' is its midpoint . Now prove that OM is perpendicular to AB

If M denotes the midpoint of the line segment joining A(4 i+5j-10k) and B(-i+2 j+k), then the equation of the plane through M and perpendicular to AB, is

The line segment joining any two points on the circumference of circle is :

Draw a line segment of length 9.5 cm and construct its perpendicular bisector.

Draw any angle with vertex O. Take a point A on one of its arms and B on another such that OA = OB, Draw the perpendicular bisectors of O̅A and O̅B. Let them meet at P. Is PA = PB?
