Question
Calculate the area and the perimeter of the triangles formed by the following set of vertices.$$\{(-1,1),(3,1),(3,-2)\}$$
Step 1
The base and the height are the two sides that form the right angle. By looking at the coordinates, we can see that the base is the distance between the points (-1,1) and (3,1), which is 4 units. The height is the distance between the points (3,1) and (3,-2), Show more…
