Diagram : abc
Base is base of a triangle from which perpendicular distance to tip of the
triange is known
Height is perpendicular distance from base of the triangle to tip of the
triangle
Area is the total surface area of the triange
Side a, b, c is one of the sides of the triangle usually represented as a,
b, c
Area can be calulated using base and height for all three sides length. It works
other way too which means given base and area height of the triangle can be calculated
or given area and other two sides the third side can be calculated
