Show that of all line segments drawn from a given point not on it, the perpendicular line segment is the shortest.

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

Prove that the angle between the two tangents drawn from an external point to a circle is supplementary to the angle subtended by the line-segment joining the points of contact at the centre.

Prove that the angle between the two tangents drawn from an external point to a circle is supplementary to the angle subtended by the line segment joining the points of contact at the centre.

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

The end points of a line segment are (2, 3), (4, 5). Find the slope of the line segment.

Show that the line segments joining the mid-points of the opposite sides of a quadrilateral bisect each other.

Show tha the line segments joining the mid points of the opposite sides of a quadrilateral bisect each other.

Show that the line through the points (1, -1, 2), (3, 4, -2) is perpendicular to the line through the points (0, 3, 2) and (3, 5, 6).

There are n( gt2) points in each of two parallel lines Every point on one line is joined to every point on the other line by a line segment drawn within the lines . The number of points (between the lines) in which these segments intersect is :

AD and BC are equal and perpendiculars to a line segment AB. Show that CD bisects AB.
