      MATHEMATICS - 10TH CLASS -CIRCLES - TANGENTS explained by Planetary Clock.       TANGENTS TO A CIRCLE . let us suppose. In a plain, there is a circle and a line  they are tree ways in the bottom of the map see in the pic (1). in the pics there is circle represented by the planetary clock and a small sketch represents to a line.                                                                        pic No.(1) that line is not condemned to a circle. in the above pic there is no line touch to the circle by the planetary clock.    In pic (2), the line break down at the one points that is A . it is called TANGENT to a circle pic No. (2)              the line (L) break down the circle at the two points those are poi...

                         NEWTON GRAVITATION LAW: according to Newton theory , everybody attracts to another body. In the solar system sun attracts remaining bodies rotates around it.

MATHEMATICS AREAS: The formula of SQUARE how to find by the Planetary Clock. Let us take a Planetary Clock and a paper made of a SQUARE cuts into four small equal   sided  SQUARE shape paper pieces and puts it on the Planetary Clock.   i will tell them with pics No.1,2,3,4,5,6                                                                         pic No.1                                                                           pic No.2                                             ...
