Best Answer

Depending on what you're solving for in a triangle determines which formula you're going to use. The equations (formulas) are as follows:

Finding a missing side of a Right Triangle: a2 + b2 = c2

a = leg1 or side1

b = leg2 or side2

c = Hypotenuse

Interior Angles of a Triangle: x + y + z = 180º

Perimeter of a Triangle: P = S1 + S2 + S3

Area of a Triangle: A = ½bh OR A = (bh)/2

When finding the area of something your unit of measurement is always going to be squared. Ex: 5 in2

In a periodic equation a triangle can be used to represent the given change of something.

mathematical equation

Depends on what formula.

a delta's a triangle, so the area of a triangle is bh/2

A quadratic equation is univariate: it has only one variable. A quadratic equation cannot have two variables. So, if b and c are known then it is a quadratic equation in a; if a and b are known it is a quadratic in c.Another Answer:-The question given is Pythagoras' theorem formula for a right angle triangle
