For a right angle triangle if two sides are given then the third side can be found by using Pythagoras' theorem.

a2+b2 = c2 where a = base, b = height and c = hypotenuse

By rearranging:

c2-a2 = b2

c2-b2 = a2

What is the purpose of the Pythagorean theorem in mathematics?

The purpose of the Pythagorean theorem in mathematics is to calculate the length of the sides of a right-angled triangle. It helps in finding the unknown side lengths by using the relationship between the squares of the triangle's sides.


Any problem of geometry which should be solve by algebra as well as geometry?

well, i think the answer to your question is getting the measurement of the side using the Pythagorean Thereom, with the formula:c2=a2+b2.


How do you determine an unknown side in a geometrical shape when given one measurement and the volume or surface area?

Substitute the information that you are given into the formula.


How do you find the unknown height of a triangle?

If you know the other two sides of the triangle, name one a2 & the other one b2 (it doesn't matter which side you call what, just make sure you plug in the 2 sides) and the unknown side (the hypotenuse) c2. The Pythagorean Theorem is a2 + b2 = c2. Try that & see if you get the answer.


How do you find the unknown side length of a shape?

To find the unknown side length of a shape, you can use various mathematical principles depending on the shape and known information. For triangles, you might apply the Pythagorean theorem or trigonometric ratios if you have angles and one side. For polygons, you could use properties like the sum of interior angles or the relationships between sides. Additionally, algebraic equations can be set up if you have sufficient information to solve for the unknown length.


How do you solve for the unknown side length for a right triangle?

you must have at least 2 given sides or a given angle you can use the pythagorean theorem formula c² = a² + b² try the link below for a computation


What is the pythagorean principle?

The pythagorean principle is A squared + B squared = C squared. This is applyed when solving side lengths of triangles.


What is pythagorean thorem for?

The Pythagorean theorem is used to find the length of a certain side in a right triangle. If you know the length of two sides of a right triangle, you can use the Pythagorean theorem, a2+ b2 = c2, to find the length of the other side. In the formula, c is the hypotenuse, which the longest side of the triangle.


How is the pythagorean therem used?

It is used to find the unknown 3rd side of a right angle triangle when its other 2 sides are given and Pythagoras' theorem is:- a2+b2 = c2 whereas a and b are the sides of the triangle with c being its hypotenuse or longest side


How do you work out pythagorean theorem with only one side?

You cannot.
