basic parts of a quadrilateral

A line parallel to one side of a triangle divides the other two sides into parts of equal proportio..

Basic Proportionality Theorem (B.P.T.) will be more useful in the topic 'SIMILARITY'. Division of a line segment into equal parts. Divide a line segment of length 8.4 cm into 5 equal parts. AB = 8.4 cm 1. Draw AB = 8.4 cm and through A draw another line AX at an acute ..

Radius of the circle is 20 cm. CD = 32 cm. AB = 32 cm . Find the area of the remaining part of the circle if quadrilateral ABCD is removed from it. => 976 sq.cm or 974 sq.cm or 488 sq.cm or 244 sq.cm..

It represents nearly 80% of the total RNA in the cell. It always occurs bound to basic proteins in ribosomes. It takes part in assembling the amino acids brought by tRNA, into a polypeptide chain, based on the sequence of codons in mRN..

When light passes through a substance or gas, a part of it is absorbed and the rest scattered away. The basic process in scattering is absorption of light by the molecules followed by re-radiation in different direction..

- Newton's Law of Gravitation and Einstein's Theory of Relativity were remarkable inventions in the world of Physics that changed the world. Physics is essentially a part and parcel of our everyday life and an understanding of its basic concepts is important to study advanced co..

Logical reasoning Geometric proofs Euclidean/non-Euclidean geometries Formal/informal proofs Conditional statements Pythagorean Theorem Intersection of a plane with 3-d figures Congruence, similarity, triangle inequality theorem Properties of quadrilaterals, circles, parallel li..

In this, the cancerous parts of the body are exposed to ionising radiations like x-rays, which kill the cancerous cells. It gives good results in skin, lip, mouth and cervix cancers. Radiation therapy is used in 80% of cancer patients. The basic principle here is to bombard the..

Most experiments in physics require the observations made to be quantitative rather than qualitative. If observations are only descriptive or qualitative, they are likely to be imprecise and could cause disagreements between experimenters. For example, scientists cannot merely say that an object i..

Atomic structure - Although Dalton's theory of the existence of atoms was published in 1808 there was no clear idea of what an atom might look like until the early part of the twentieth century. With the advent of electricity and phenomenon of spectrum, experimentation underwent a change ..
