False it can work with non right angles triangles too
The equation that represents the line is:

Step-by-step explanation:
We have to observe the graph to find the points on line
So the points on line are:
(x1,y1) = (4,6)
(x2,y2) = (-2,1)
First of all we have to find the slope

Equation of line is given by:

Putting the value of slope

Putting (4,6) in the equation

Putting the value of b

Hence,
The equation that represents the line is:

Each side is 1.25inches I don't know if this answers your question but i hope it helps
It’s True because of 5 square is equal to 25
Than (-5) square is also get the same value as 5^2
I’m sorry, I don’t know perpendicular but I would love to help.
