Mark four points on a sheet of paper. Label them P,Q. R and S.

Mark the following points on a sheet of paper. Tell how many line segments can be obtained in each case: Two points A, B. Three non-collinear points A, B, C. Four points such that no three of them belong to the same line. Any five points so that on three of them are collinear.

Mark a point on a sheet of paper and draw a line passing through it. How many lines can you draw through this point?

Mark three points and label them as M,N,and O.

Observe the following figures and identify the structures of parts labelled as P, Q, R and S.

If P(2,-1), Q (3,4), R(-2,3) and S (-3,-2) are four points in a plane, show that PQRS is a rhombus but not a square.

If P(2,\ -1),\ \ Q(3,\ 4),\ \ R(-2,\ 3) and S(-3,\ -2) be four points in a plane, show that P Q R S is a rhombus but not a square. Find the area of the rhombus.

A straight line through the vertex P of a triangle P Q R intersects the side Q R at the points S and the cicumcircle of the triangle P Q R at the point Tdot If S is not the center of the circumcircle, then 1/(P S)+1/(S T) 2/(sqrt(Q SxxS R)) 1/(P S)+1/(S T) 4/(Q R)

What are (P),(Q),(R) and (S)?

A positive point charge is placed at P in front of an earthed metal sheet S.Q and R are two points between P and S as shown in the diagram. If the electric field strength at Q and r are respectively E_(Q) and E_(R) , which one of the following statement is // are false?
