If the vector a=[ x+1,2), b=[1, x], then a is vertical b if and only if

If the vector a=[ x+1,2), b=[1, x], then a is vertical b if and only if

[X+1,2)[1, x ]=0
X+1+2x=0
X=-1/3

How to deduce the necessary and sufficient condition a*b=0 of vector a perpendicular b?

How to prove that a vector is perpendicular to a plane or a straight line is perpendicular to a plane

It can be proved by finding the intersection of the plane can be found in the plane, and then as long as the intersection of the two vertical lines can be found in the plane then it can be proved

As long as the intersection of a line and a plane can be found on the plane, and then as long as the intersection of two perpendicular lines can be found on the plane then it can be proved

It can be proved by finding the intersection of the plane can be found on the plane, and then as long as the intersection of the two vertical lines on the plane can be found.
