To find the perimeter of a triangle with vertices at (3, 3), (1, 5), and (2, 1), you calculate the distance between each pair of vertices and then sum up those distances.
The distance between two points and in a coordinate plane can be found using the distance formula:
-
Distance between (3, 3) and (1, 5):
-
Distance between (1, 5) and (2, 1):
-
Distance between (2, 1) and (3, 3):
Now, sum up the distances to find the perimeter:
This is the perimeter of the triangle with the given vertices.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- Circle A has a center at #(1 ,1 )# and a radius of #1 #. Circle B has a center at #(2 ,-3 )# and a radius of #5 #. Do the circles overlap? If not, what is the smallest distance between them?
- An isosceles triangle has sides A, B, and C with sides B and C being equal in length. If side A goes from #(4 ,9 )# to #(8 ,5 )# and the triangle's area is #64 #, what are the possible coordinates of the triangle's third corner?
- A line passes through #(3 ,4 )# and #(4 ,7 )#. A second line passes through #(7 ,3 )#. What is one other point that the second line may pass through if it is parallel to the first line?
