Question

The co-ordinates of the mid-point of CD is (1, 10)
If true then enter $1$ and if false then enter $0$

Answer 1

Plot
the points, A, C and D. Join them using straight lines to complete the square.
Hence B $=(4,4)$.
The co-ordinates of the mid-pt of a segment joining (a,b) and (c,d) are $\left(\right(a+c)/2,(b+d\left)/2\right)$.
Hence, mid point of CD $=(1,10)$
