The word Geometry contains two words, one is ‘Geo’ and other is ‘metron’. Geo means earth and metron means measurement. So geo-metry means to measure the earth. This word
has been derived from the Greek word ‘Geo-metron’ which means to measure the earth. The idea of geo-metry began when men felt the need to measure their lands while buying and selling. Geo-metrical ideas have developed over centuries to cater to needs in art, architecture etc. In this part we use geo-metrical construction.
Just as arithmetic has numbers as its basic elements (or building blocks) , algebra has numbers, alphabets and the four fundamental operations of addition, subtraction, multiplication and division as its basic elements ( or building blocks) , geo-metry too has its own building blocks. These building blocks are Point, Line and Plane.
In this section ask-math
explains you according to the topics and according to the grade in detail. Here we have covered the topics such as lines, angles, triangles, quadrilateral etc. ask-math
also explains how to write geo-metrical proofs and it also explain you about the construction.
Geo-metry– Table of Contents
Basics of geo-metry : The word 'geo-metry' means measurement of the earth. Various shapes and figures with which we deal in Geo-metry are called geo-metrical figures.
Quadrilaterals : which are basically shapes like square,rectangle,rhombus…etc
Triangles : Introduction to Triangles,types of triangles and congruence of triangles using postulates
Similarity : Geo-metric figures having the same shape but different sizes are known as similar figures.
Pythagorean Theorem : It states that the square of hypotenuse is equal to the sum of the squares of other two legs.(a2 + b2 = c2).
Circles : The round shape figure is called Circles.
Geo-metric Constructions : In Geometry, it means to draw shapes, angles or lines accurately.
Special right triangle : Recognizing special right triangles in geo-metry can help you to answer some questions quicker.
