Just find the midpoint of opposite corners
Consider the rectangle with sides of length a and b. The length of a diagonal is then sqrt(a2+b2) The two diagonals cross at the midpoint or where the length of the line from one vertex to the center is one half of a diagonal or (0.5)[sqrt(a2+b2)].
1- Consider you have Point A(XA,YA) corresponding to the upper left coordinate of the rectangle and you have Point B(XB, YB) corresponding to the lower right coordinate of the rectangle, then, coordinates of the center Point C (XC, YC) is calculated:
XC = XA + (XB-XA)/2
YC = YA - (YA-XB)/2
2- Consider you have Point A(XA,YA) corresponding to the upper left coordinate of the rectangle and the width (W) and height (H) of the rectangle, then, coordinates of the center Point C (XC, YC) is calculated:
XC = XA + (W)/2
YC = YA - (W)/2

Does a rectangle have point symmetry?
Yes. In 3 dimensions, a rectangle has 3 C2 axes perpendicular to each other and an inversion center at the center of the rectangle. There are also reflection planes along each of the C2 axes; this makes the point group of the rectangle D2h.
What are the coordinates of the fourth vertex of a rectangle that has three vertices at 4 -5 and 4 -3 and 5 -3?
The vertex is at (5, -5).
How do you calculate the coordinates of the center of the square?
The center of a square is half-way up one side and half-way along the adjacent side, and the sides are the same in a square, so you might say, "1/2A, 1/2A" for the center of a square with one corner at the origin of the axes and having size of A.
Rectangle has how many faces?
A rectangle has NO faces. A rectangle has FOUR(4) Sides.
The angles in a rectangle are all?
... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.
What are the coordinates of the fourth vertex of the rectangle?
It depends on what the coordinates of the first three vertices are!
Are the midpoints the vertices of a rectangle?
No- the vertices of a rectangle are the four coordinates (corners) not the midpoints.
What are the 4 coordinates of a rectangle?
90 Degrees exact
What is the Formula for center of gravity of a rectangle?
The formula for the center of gravity of a rectangle is: X = (W/2) and Y = (H/2), where X is the distance from the side of the rectangle to the center and Y is the distance from the top of the rectangle to the center, W is the width of the rectangle, and H is the height of the rectangle.
What are the center coordinates of a rectangle whose height is 40 width is 30 and with starting points at 25 and 25?
(40, 45) The center point is half way along the width and half way up the height; thus the center coordinates are: (25 + 30/2, 25 + 40/2) = (25 + 15, 25 + 20) = (40, 45)
How do you find the area of a rectangle if you have coordinates?
multiply width times length
Point G of the rectangle is at the origin.What are the coordinates of point E?
-a, b
What is the first step to finding a triangles center of gravity?
The first step to finding a triangle's center of gravity is to calculate the average of the x-coordinates and y-coordinates of the triangle's vertices. This will give you the coordinates of the centroid, which is the point where the center of gravity lies.
Where is center of rotation of rectangle?
centre it and that is the answer
What are the coordinates at the center of Australia are?
-24.046464, 135.864256
What are the coordinates of the center of a cube?
Without further information, the coordinates could be any ordered triplet.
How do you find the area of a rectangle if you have the coordinates?
you look how the difference is and then you multiply it by the other number and then you are answer should be the product.
