Provided:-
- Centroid of the triangle = (2,3)
- Two of the vertices of triangle = (5,6) and (-3,4)
To FinD:-
- The third vertex of the triangle?
How to solve?
Here, we have been given Centroid of the triangle which is the intersecting point of three meridians of the triangle.
- The centroid of the triangle is given by where (x1, y1), (x2, y2) and (x3, y3) are the vertices of the triangle.
So, By using this formula, Let's solve the Q.
Solution:-
We have,
- Vertices of the triangle (5,6) and (-3,4) and centroid of the triangle (2,3)
Let,
- Assume the third vertex be (x3, y3)
By comparing both sides,
|| Evaluating x3 and y3 ||
➝ 5 + (-3) + x3 /3 = 2
➝ 2 + x3 = 6
➝ x3 = 4
✒ x coordinate of third vertex = 4
&
➝ 6 + 4 + y3 /3 = 3
➝ 10 + y3 = 9
➝ y3 = -1
✒ y coordinate of third vertex = -1
☀️ So the coordinates of the third vertex of the triangle is (4, -1) [Answer]
