Pythagorean Theorem

Pythagorean theorem states the relationship between the lengths of the sides of a right triangle.

🗨️

a b

is the hypothenuse lenght .

are the lenght of the sides.

a²+b²=c²

Theorem: The sum of the squared legs of a right triangle equals to the hypothenuse squared.

Calculation of Distance

The distance, d, between two points in a coordinate plane can be calculated using the Pythagorean Theorem.

Change of x

Change of y

|y₂-y₁|

|x₂-x₁|

is the lenght of the other leg.

is the lenght of one leg.

(x₁,y₁) and (x₂,y₂)

Definition: Distance betweenis:

(x₁,y₁)=(3,4); (x₂,y₂)=(7,1)

d=5

Example 1: Calculate the distance between points (3, 4) and (7, 1)

Let's see some examples:

Practice

(x₁,y₁)=(-1,-2); (x₂,y₂)=(5,6)
