the straight line summary

Summary - The equation of a straight line parallel to x-axis and at a distance h from it is given by y = h. The equation of the straight line parallel to y-axis and at a distance k from it is given by x = k. The equation of the straight ..

An acute angle has a measure less than 90 o . A Right angle has a measure of 90 o . An Obtuse angle has a measure greater than 90 o but less than 180 o . A Straight angle has a measure of 180 o . A reflex angle has a measure greater than 180 o . Adjacent angles have a common vert..

Inertia is the inability of material body to change, by itself, its state of rest or of uniform motion in a straight line. Mass is a measure of inertia Newton's first law of motion: A body continues in its state of rest or of uniform motion along a straight lin..

Electric charge is a basic property of all matter. Unlike charges attract, like charges repel. Conductor allow flow of electric charges through them while insulators don't. Electric charges have three basic properties (a) Additivity (b) Quantisation (c) Conservation Coulomb's law: the ..

Adjacent angles have a common vertex and a common arm. A pair of angles, the sum of whose measures is 90 o , are complementary angles. A pair of angles, the sum of whose measures is 180 o are supplementary angles. When a pair of angles are adjacent and also supplementary, they are said to form a li..

>Law of conservation of energy states that the total energy of an isolated system cannot change. A collision is said to take place when either two bodies physically collide against each other or when the path of one body is changed by the influence of the other body. A collision is said to be an el..

Ray optics is also called geometrical optics as it uses the geometry of straight-line paths (rays) to explain the optical phenomena. Ray optics, infact, is the limiting case of wave optics. This means for most practical purposes, we can ignore the deviation from straight-line..
