Question

Which statement is true of every plane in three-dimensional space?

Answer 1

Every plane must have three intercepts.

proof, every  point P in a plane in three-dimensional space is written as  P=(x, y, z), x, y and z are intercepts.

Answer 2

Answer:

option A is correct.(Every plane must have three intercepts.)

Step-by-step explanation:

" Three-dimensional space (also: 3-space or, rarely, tri-dimensional space) is a geometric setting in which three values (called parameters) are required to determine the position of an element (i.e., point). This is the informal meaning of the term dimension "

The intercept form of the equation of plane in 3-D is given by:

$\dfrac{x}{l}+\dfrac{y}{m}+\dfrac{z}{n}=1$

Where l,m,n are intercepts of x,y,z axes and a plane respectively.

Hence, we require all the three intercepts of a every plane.

Hence, option A is correct.
