To find the perimeter of the triangle with vertices at (7, 3), (1, 5), and (2, 1), you need to calculate the sum of the lengths of its three sides using the distance formula.

The distance formula between two points ((x_1, y_1)) and ((x_2, y_2)) is given by:

[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ]

Using this formula, calculate the distances between each pair of points, then sum them up to find the perimeter.

- A line passes through #(4 ,3 )# and #(2 ,6 )#. A second line passes through #(1 ,8 )#. What is one other point that the second line may pass through if it is parallel to the first line?
- A triangle has corners at #(4 ,3 )#, #(8 ,6 )#, and #(7 ,1 )#. How far is the triangle's centroid from the origin?
- A line passes through #(2 ,9 )# and #(5 ,6 )#. A second line passes through #(3 ,8 )#. What is one other point that the second line may pass through if it is parallel to the first line?
- Circle A has a center at #(-2 ,-1 )# and a radius of #3 #. Circle B has a center at #(-8 ,3 )# and a radius of #2 #. Do the circles overlap? If not what is the smallest distance between them?
- Circle A has a center at #(3 ,4 )# and an area of #16 pi#. Circle B has a center at #(8 ,1 )# and an area of #40 pi#. Do the circles overlap?
