Question

Points A and B have symmetry with respect to the
origin O. Find the coordinates of B if A is the point:
a) (3, 4) c) (a, 0)
b) (0, 2) d) (b, c)

Answer 1

for any point (a,b) , the image of (a,b) with symmetry with respect to the origin would yield the point (-a,-b)

so for (3,4) ----> (-3,-4)

I will let you do the others.
