# Why the Pythagorean theorem is important?

The discovery of Pythagoras’ theorem led the Greeks to prove the existence of numbers that could not be expressed as rational numbers. For example, taking the two shorter sides of a right triangle to be 1 and 1, we are led to a hypotenuse of length , which is not a rational number.

## What is interest in financial maths?

Interest is the charge for borrowing money. Simple interest is interest paid only on the initial amount borrowed and not on past interest. It is common practice to call the amount deposited the Capital, C, the rate, r, of interest per year (as a percentage) and the length of time the money is deposited for, t in years.

## What is the application of mathematics in daily life?

Geometry, algebra, and calculus can help students solve chemistry problems but practical sciences, such as engineering and computer science, also benefit from maths. For example, pupils may have to use complex equations and algorithms when designing and writing computer programs.

## What is the math formula for interest?

Simple Interest Formulas and Calculations: Use this simple interest calculator to find A, the Final Investment Value, using the simple interest formula: A = P(1 + rt) where P is the Principal amount of money to be invested at an Interest Rate R% per period for t Number of Time Periods.

## What type of triangles are proved by the Pythagorean Theorem?

Apply the converse of Pythagorean Theorem. Since the square of the length of the longest side is the sum of the squares of the other two sides, by the converse of the Pythagorean Theorem, the triangle is a right triangle. A corollary to the theorem categorizes triangles in to acute, right, or obtuse.

## How do you prove a right triangle?

Proof of Right Angle Triangle Theorem Theorem:In a triangle, if square of one side is equal to the sum of the squares of the other two sides, then the angle opposite the first side is a right angle. Hence the theorem is proved.

## What is Gougu Theorem?

The Gougu Theorem states that for a right triangle, with legs of lengths $$ $$ b , and a hypotenuse of length $$ $$ You can move the purple points to change the size and orientation of the triangle. In the box below, explain what this theorem is saying VISUALLY in terms of the shapes shown in the image.

## What does theorem mean?

1 : a formula, proposition, or statement in mathematics or logic deduced or to be deduced from other formulas or propositions. 2 : an idea accepted or proposed as a demonstrable truth often as a part of a general theory : proposition the theorem that the best defense is offense.

## What is the conclusion of Pythagoras Theorem?

A right-angled triangle can be identified given the length of the longest side squared is equal to the sum of the other two sides squared. The length of any side of a right-angled triangle can be determined given the length of any two sides.

## What does Pythagorean theorem mean?

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

## How do you solve interest on a loan?

Simple interest Calculation: You can calculate your total interest by using this formula: Principal Loan Amount x Interest Rate x Time (aka Number of Years in Term) = Interest. You might encounter simple interest on short-term loans.

## How do you use the Pythagorean theorem of a right triangle?

Right Triangles and the Pythagorean Theorem

- The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
- The side opposite the right angle is called the hypotenuse (side c in the figure).

## Why is it called the Pythagorean Theorem?

The Pythagorean Theorem was one of the earliest theorems known to ancient civilizations. This famous theorem is named for the Greek mathematician and philosopher, Pythagoras. According to legend, Pythagoras was so happy when he discovered the theorem that he offered a sacrifice of oxen.

## What is the longest side of a right triangle?

hypotenuse
