Use the distance formula to find the distance between point A(-5, 4) and point B(7, -5)

Step-by-step explanation:

Given,

A( -5 , 4 )⇒ ( x₁ , y₁ )

B ( 7 , -5 )⇒ ( x₂ , y₂ )

Finding distance between these two points

plug the values

Calculate the sum

Evaluate the power

Add the numbers

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
