How do you use coordinate geometry to prove that a triangle is a right triangle

Step-by-step explanation:

with the given points, first you need to find their lengths. using distance formula of root ((x2-x1)^2 + (y2+y1)^2).

you'll get three values

then you need to use Pythagoras theorem and equate the hypoteneus square with the sum of the squares of the other sides. or, h^2 = A^2+B^2.

I hope you understand

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
