Answer:
The coordinates of the fourth vertex are (8,5)
Explanation:
We need to take note that a rectangle is a shape that has 4 sides, with two of them of equal length.
It will also help if we can visualize the points on the graph.
We are given the location of three of the four vertices. These are (6,3), (6,5) ,and (8,3). Let the 4th Vertice be (x,y)
The length of the triangle can be obtained by subtracting the y-coordinates of the vertices.
(6,3) - (6,5)
This will be +3 and +5
5-3 =2
Therefore, the length of the triangle is 2 units on the left side.
Recall that the length of the left side has to be equal to the length of the right side.
Therefore
y-3 =2
y = 5
We will repeat the same process to get the x-coordinate from the breadth
Breadth = 8-6 =2
x-6 =2
x=8
Hence the x = 8
Therefore, the coordinates of the fourth vertex are (8,5)
