Tangents are drawn from a point P to two circles of radii 7 cm and 9 cm respectively. Find PT : PS. => 9 : 8 or 9 : 7 or 1 : 1 or 7 : 9..

ΔPQR similar to ΔMNS. If the medians PT and MK are in the ratio 2 : 5, then find the ratio of areas of ΔPQR to ΔMNS => 2 : 5 or 5 : 2 or 4 : 5 or 4 : 25..

Melting Points and Boiling Points - The melting and boiling points of group 14 elements are much higher as compared to those of group 13 elements. Explanation: It is because the atoms of group 14 can form four covalent bonds with each other and, therefore, there are st..

A point A and a point M. We are required to construct the reflection of point A through a point M. (i) Join AM and produce it. (ii) Obtain point A' on the line so that AM = A'M. (iii) Then A' is the image of A in point M..

If two or more points lie on the same line, then they are called collinear points..

(O) The point at which the incident ray strikes the surface of separation of the two media is called the point of incidenc..
