Parallel segments

Find the magtiude and direction of a force vector acting on a unit length of a thin wire, carrying a current I = 8.0 A , at a point O . If the wire is hent as shown in (a) Fig with curvature radius R = 10 cm (b ) Fig the distance between the long parallel segments of the wire being equal to l = 20 cm .

Prove that the line segment joining the points of contact of two parallel tangents of a circle, passes through its centre.

Prove that the segment joining the point of contact of two parallel tangents passes through the centre.

Point O is the centre of a circle . Line a and line b are parallel tangents to the circle at P and Q. Prove that segment PQ is a diameter of the circle.

Two non - parallel line segments will always intersect.

Identify parallel line segments in each of the figures given below :

Triangle a plane figure formed by three non- parallel line segments is called a triangle.

TRIANGLE A plane figure formed by three non-parallel line segments is called a triangle.

PQ and RS are two equal and parallel line segments. Any point M not lying on PQ or RS is joined to Q and S and lines through P parallel to QM and through R parallel to SM meet at N. rove that line segments MN and PQ are equal and parallel to each other.
