Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.
If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.
Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.
Solving for the coordinates gives x2 = 10, y2 = 13
Answer:
Quadrilateral ABCD is a <u>parallelogram</u>
if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a <u>kite</u>
Step-by-step explanation:
without solving, im guessing that quad ABCD is a paralellogram (//gram)
lets test this theory
see if the slope of AB and CD, and BC and AD is the same
slope AB and CD
AB:
-7--4/11-9
=-3/2
CD:
-1--4/11-13
=3/-2
=-3/2
slope is the same
slope BC and AD
BC:
-4--1/9-11
=-3/-2
=3/2
AD:
-7--4/11-13
=-3/-2
=3/2
slope is same
because 2 pairs // sides ---> //gram
if the vertex C( 11, -1 ) we’re shifted to the point C ( 11, 1 ), quadrilateral ABCD would be a kite
