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.

S 6 5 T 8 3 U 12 -1 coordinates are the vertices of a triangle?
The coordinates are the vertices of a triangle since they form three points.
What is the perimeter of a triangle with vertices located at (1 4) (2 7) and (0 5) rounded to the nearest hundredth?
1.00
Why is it not possible to draw a diagonal of a triangle?
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
What shape has 1 face 0 edges and 0 vertices?
sphere
What shape is this 0 vertices 0 edges 1 faces?
It could be a sphere
If the vertices are -3 3 3 5 and -1 0 what is the perimeter?
The perimeter of a triangle with vertices at (-3,3), (3,5), and (-1,0) is 16.3334.
What is the area of the triangle represented by the vertices A(1 1) B(7 1) and C(7 9?
It is a right angle triangle with an area of: 0.5*7*9 = 31.5 square units
How do you find the area of a triangle whose vertices have the coordinates ( -1 -1) (-13) and (5 -1)?
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
