If the vertices are at (0, -2) (8, -2) and (9, 1) on the Cartesian plane plane then by using the distance formulae and trigonometry the area of the triangle works out as 12 square units.
The coordinates are the vertices of a triangle since they form three points.

Because all the vertices are already joined together. The formula for the diagonals of a polygon is: 1/2*(n2-3n) where n is the number of sides A triangle has 3 sides and 1/2*(32-9) = 0
sphere
It could be a sphere
The perimeter of a triangle with vertices at (-3,3), (3,5), and (-1,0) is 16.3334.
It is a right angle triangle with an area of: 0.5*7*9 = 31.5 square units
If you mean vertices of: (-1, -1) (-1, 3) and (5, -1) then when plotted on the Cartesian plane it will form a right angle triangle with a base of 6 units and a height of 4 units. Area of triangle: 0.5*6*4 = 12 square units

To find the third vertex of the equilateral triangle with vertices at (0, 1) and (4, 3), we can use the fact that the distance between all three vertices must be equal. The midpoint of the segment connecting (0, 1) and (4, 3) is (2, 2). The third vertex can be found by rotating the segment around this midpoint by ±60 degrees. The third vertex is either (1, 4) or (3, -2).
