Area of triangles its properties & formulae

A triangle is polygon with three edges three vertices and three angle. It is a plan 2D figure .

There are four most important types of triangles :-

These triangles have all three sides equal in length . It also have all three angle equal .

2) Scalene triangle :-

This type of triangles don't have any equal sides.

3) Isosceles triangle :-

This type of triangle have two equal sides .

4)Right angle triangle :-

this type of triangles have one angle as 90 degree .

Areas Related To Triangle :- (Formulae)

Area of triangle is defined as total space that is enclosed by any particular triangle.

To find the area of triangle there are some formulae :-

1) area of triangle = 1/2 *b*h

2) area of triangle = under root s (s-a) (s-b) (s-c)

3) area of equilateral triangle = under root 3/4 *(a^2)

Properties Of Triangle :-

1) The sum of all angles of a triangle is 180 degree.

2) An exterior angle of a triangle is equal to the sum of its two interior opposite angle .

3) The sum of the length of any two sides of triangle is always greater than the third side.

4) Angle opposite to longer side is larger.

5) Side equal to greater angle is longer.

6) The exterior angle of a triangle always add up to 360 degree.
