Example 1:
Find the perimeter of a triangle with vertices (2,4) (-1,3) and (2, -3).
(show your work on graph paper)

I got an answer of 7+ 3 sqrt(5) + sqrt(11) which is in simplest radical form. Is that correct?

use pythagoras theorem to find length of each line
sqrt(1^2 + 3^2)  = sqrt 10  is one line

anonymous · Answer

I can't because its not a right triangle

anonymous · Answer

you are forming a right-angled triangle i'll draw it

anonymous · Answer

sorry i understand what you are saying now. you split the triangle into two right triangles right?
