Here are online calculators generators and finders with methods to generate the triples to investigate the patterns and properties of these integer sided right angled triangles. In a right triangle if one leg is taken as the base then the other is height so the area of a right triangle is one half the product of the two legs. M what is the missing reason in step 8. Part one deals with elementary algebra part two provides a basic course in trigonometry and part three considers elements of two dimensional co ordinate geometry including solid geometry and mensuration.
