Question 1130388
How do i GRAPH POINTS A(-2,1)) B(-2,6), C(1,3)
------------
Do you have graph paper?
the Origin, where the x and y-axes cross is (0,0)
The x-axis is "horizontal" - left to right, and the y-axis is "vertical," up and down.
For A(-2,1), plot 2 units left and 1 unit up.
Same for B and C.
-------------------
How then do I find the length of segment BC
{{{L = sqrt(diffy^2 + diffx^2) = sqrt((-2-1)^2 + (6-3)^2) = sqrt(9+9) = 3sqrt(2)}}}
------------------------

How do I find the perimeter of triangle ABC
Find the 3 side lengths and add them.
======================

Lastly, how do I find the length to triangle ABC
IDK what that means.
