If you mean vertices of (-1, 4) (2, 7) and (1, 5) then it is an isosceles triangle with a perimeter of square root of 18 plus square root of 5 plus square root of 5 which is about 8.715 rounded to three decimal places.
The vertices of a triangle are the endpoints. In other words, when the sides of the triangle intersect, they form a vertex of a triangle. A triangle has a total of three vertices.
The perimeter of a triangle with vertices at (-3,3), (3,5), and (-1,0) is 16.3334.

If one of the three interior angles is 90 degrees then it is a right triangle.

A triangle has 3 sides and 3 vertices. Strictly speaking, the interior of the triangle is not part of the triangle so it has no faces. However, a triangular lamina will have two faces - one from above and one from below.
