AREA OF TRIANGLES

Mathematics branch which deals with the calculation of length of lines area and

volume of different figures scope it is widely applied in various branches of

Engineering, a chemical engineer has to find the volume or capacity of a plant

civil engineer has to find area and volume in ember market Canal digging or Dam

work IN electrical engineer has to depend upon this branch of mathematics which

drops man and a designer or an electrical supervisor very often use

calculating resistance are capacity of a conductor in the in the same way it

mensuration  in his work 

If we dismantle any complicated machine or its parts we will find the machine has

been separated into different simple plain or solid figures like rings

cylinders squares and prisms

Plane figure

Plane figure are those figures which occupy and area with only two dimension room

flowers grassy plots and Tin sheets are examples of plane figures while the

volts wooden box and Dam are examples of solids

solid figure are those which occupy space with three dimensions shaft flywheel

Triangles  

A triangle is a plane figure bounded by three straight lines this the straight

line AB, BC and CA which bound triangle ABC are called its side the side BC may

be regarded as the base and add as the height .

Kinds of Triangle

There are 6 types of triangle 3 e of them are classified according to their sides and

their remaining three are according to their angles

Triangle classified into 3 angles 

 Right Angle Triangles

Angle of triangle is a right angle 90 then it is called a right angle triangle that side

opposite to right side is card by the hypotenuse and remaining other two sides

on bases and altitude.

Acute angle 

Acute angle triangle If all the three angles of a triangle are less than 90 degrees then the triangle is called acute angled

Obtuse Angle Triangle 

If one angle of a triangle is Obtuse generate than 90 triangles is called Obtuse Triangle.

Triangle classified according to their sides

Scalene triangle

a triangle in which all sides are of different lengths is called scalene line

Triangle. 

ISO Scalene Triangle 

If two sides of a triangle are equal the triangle is called ISO scalene.

Equilateral Triangle 

If all the three sides of a triangle are equal length the triangle is called

equilateral triangle.

Perimeter

The perimeter of a closed plane figure the total distance around the edges of a figure

Perimeter of a triangle with sides  A B &C . Few lines perimeter of triangle is =( a + b + c )units
