What is the area of the triangle whose vertices are 0 0 0?
Area of triangle=1/2{x1(y2- y3)+x2(y3-y1)+x3(y1-y2)}hence, 1/2{0(2-0)+0( 0-0)+2(0-2)} =1/2{0+0-2} =-2/2=-1.
For what value of k the points are collinear?
3
Since the given points are collinear, it means the area of the triangle formed by them is equal to zero. Hence the value for \[k\] is 3.

What are coordinates of a triangle?
The term triangular coordinates may refer to any of at least three related systems of coordinates in the Euclidean plane: a special case of barycentric coordinates for a triangle, in which case it is known as a ternary plot or areal coordinates, among other names.
How do you find the area of a triangle with given vertices?
The formula for the area of the triangle is given by S=12[x1(y2−y3)+x2(y3−y1)+x3(y1−y2)] , where, (x1,y1),(x2,y2),(x3,y3) are the coordinates of the three vertices of the triangle. The units of the area are assumed to be square units.
How do we find area of a triangle?
So, the area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle. Example: Find the area of the triangle. The area A of a triangle is given by the formula A=12bh where b is the base and h is the height of the triangle.
How to find area of triangle if we only know vertices?
But, how can we find area of triangle if we know only the coordinates of vertices of triangle. If, we know the vertices of triangle then we can definitely use distance formula to find the length of all the sides which can enable us to use Heron’s formula to find area of triangle. But, this will become too much lengthy and tedious.
What is the area of the triangle with base 3 units?
You can make out that (0,0) is the origin, (6,0) is a point on the x-axis and (0,3) is a point on the y-axis. Hence base = 3 units and altitude = 6 units. Consequently, the area of the triangle is 9 square units.
What is the area of triangle OAB?
If we roughly sketch the points O (0,0) , A (3,0) , B (0,2) on the graph OAB form a right triangle right angled at O with OA and OB as it’s legs with OA=3units and OB = 2 units. So area of triangle OAB = (1/2)×3×2 = 3 sq.units.
