Question

Explain some points on triangles, its definition and its properties

Answer 1

a triangle word is a derivative of the Greek word try + angle which means a plane figure with three angles now the scientist had developed its definition as a plane geometrical figure which has three angles and three sides you can say that it has three edges and three vertices a triangle is as important in maths as John guttenberg is in the history of word triangle is a figure the sum of whose angle is 180 degree and it has three medians which meet at a common point we can prove in Mathematics 2 Triangles congruent and similar for which we have many criteria namely side side side side angle side right angle hypotenuse side angle angle angle and many more a triangle is a figure which is used in practical geometry and trigonometry is an important branch of mathematics which includes the measure of the angles of a triangle in ratio which we commonly se as sine cosine tangent cotangent and many more in this way a triangle is an important feature of mathematics also the diagonals of a parallelogram divides it into two congruent triangles so we can say that in geometry the very soul of geometry is the figure Triangle
