Answer:Distance AB =√17 units
CD =√53 units
Step-by-step explanation:
Distance between two points can be calculated by two ways
1) vector form: by making position vector of each point,subtract both and taking magnitude
A(1,-2,-1)
Position vecotr of point A
B(4,0,-3)
Position vecotr of point B
Distance between vector a and b
2) Cartesian form:
Distance between two points with co-ordinatesC(x1,y1,z1) D(x2,y2,z2)
