Question

show that the point A (1 - 2)b (3,6) C(5,10) and D(3,2)are the vertices of a parallelogram​

Answer 1

Answer:

You plot on the graph paper then if u see parallelogram they are the vertices....

Answer 2

Answer:

slope of line AB =6-(-2)/3-1 = 8/2 = 4

slope of line CD =2-10/3-5 = -8/-2 = 4

hence, ABIICD , Similarly prove ADIIBC

since ABIICD & ADIIBC

hence given vertices are of a parallelogram
