If the coordinates of a point, before reflection, were (p, q) then after reflection, they will be (-p, q).

How do you find the length if you have the coordinates and the midpoint?
To work out the length, you need the coordinates of both endpoints. If you have one endpoint and the midpoint, you can treat this as two endpoints and then double the answer you get to calculating the length. To calculate the length, work out the difference in x axis values and difference in y axis values. You then find the square root of (x2+y2). This is the length between the two coordinates.
How can you locate the centroid of a convex quadrilateral?
The analytical method is far from simple:Divide the quadrilateral into two triangles, say ABC and BCD.The centroid of triangle ABC is P = [(xa+xb+xc)/3 , (ya+yb+yc)/3] where (xa,ya) are the coordinates of A and so on.Label the centroid of BCD as Q and find its coordinates in a similar way.The next step is to find the areas of the two triangles.Area (ABC) = gArea(BCD) = hThen the centroid of the whole quadrilateral is the weighted average of the coordinates of P and Q, with weights g and h.Thus, if R is the centroid of the quadrilateral, thenxr = (g*xp + h*xq)/(g+h) andyr = (g*yp + h*yq)/(g+h).If you can cut out the quadrilateral the procedure is much simpler. Suspend the quadrilateral from one corner and, using a plumb line or equivalent, mark the vertical direction. Repeat from the adjacent vertex. The two lines will meet at the centroid.
How do you find the coordinates of a point?
The coordinate n-space usually consists of n mutually perpendicular axis which all meet at a point called the origin. The coordinates of any point are the distances of the point along the directions of each of these axes, in order. In 2-dimensional space, for example, there are two axes which are conventionally called the x and y axis. The x-axis is horizontal and the y-axis is vertical. The coordinates of any point are the ordered pair consisting of the distance of the point from the origin in the horizontal direction and the vertical direction. In 3-dimensional space, there are 3 axes, and so on.
Do find the x- and y-coordinates of any point on the xy-plane.?
To find the x-coordinate of a point on the xy-plane, you look at the horizontal distance of the point from the y-axis. The y-coordinate of a point on the xy-plane is the vertical distance of the point from the x-axis.
How can you find the radius of a circle with coordinates?
Work out the length of the coordinates and half it.
How do you find whether the given quadrilateral is a triangle?
Suppose a quadrilateral is given using its vertex coordinates. It will be a triangle if three vertices are collinear, that is are on the same line.

How do you find coordinates to an angle?
A point has coordinates; an angle does not.
Is it possible to find coordinates of Australia?
Is it possible to find coordinates on the map of Australia? why or why not
How can you find the radius of a circle with coordinates?
Work out the length of the coordinates and half it.
How do you measure a vector?
Measuring a vector requires a reference. You'll need something that will allow you to find direction, and a unit length so you can find magnitude. A graph is a good way to do this, and something with a standard x and y axis (Cartesian coordinates) is just the ticket. Our graph has an origin, and that can be your starting point. Starting there, and using the x-axis as zero degrees, find your angle. Then draw a segment out along that axis the appropriate length. You now have a vector with its angle (direction) and length (magnitude).
How do you find a parallelogram in a quadrilateral?
It's not a matter of 'finding' it. Either the quadrilateral is a parallelogram,or else it is not one.If the opposite sides of the quadrilateral are parallel, then it's a parallelogram.
How do you find perimeter of a quadrilateral?
A quadrilateral is a four sided figure, so sum the lengths of its four sides.
How do you find the length of a Quadrilateral when you are given two sides?
It depends on what kind of quadrilateral is. Still, you can't solve it.
