16. TRUE or FALSE Vanishing points are placed on the horizon line. 17. TRUE or FALSE If the horizon line is placed below a subject, in addition to the sides, we are likely to see the top of an object. 18. TRUE or FALSE When an object casts a shadow, the outline of the shadow will also be governed by perspective lines directed to vanishing points. 19. TRUE or FALSE When drawing an object in perspective with lines travelling toward vanishing points, all lines that are vertical in the study will stay vertical. 20. TRUE or FALSE When two sharp planes meet, the lighter one becomes still lighter as it meets the darker plane, and the darker one becomes darker as it meets the lighter one.

True/False: Determine whether each of the statements that follow is true or false. If a statement is true, explain why. If a statement is false, provide a counterexample. (a) True or False: The graph of every linear equation in $\mathbb{R}^{3}$ is a line. (b) True or False: Three distinct points determine a plane. (c) True or False: Two distinct lines in $\mathbb{R}^{3}$ always determine a plane. (d) True or False: Three concurrent lines determine a plane. (Concurrent means that the three lines intersect in a common point.) (e) True or False: If two distinct lines in $\mathbb{R}^{3}$ are not skew, they determine a unique plane. (f) True or False: If two distinct planes in $\mathbb{R}^{3}$ intersect, they intersect in a unique line. (g) True or False: If the direction vector of a line is parallel to the normal vector to a plane, the line and plane are parallel. (h) True or False: Let $\mathcal{P}_{1}$ and $\mathcal{P}_{2}$ be distinct planes with normal vectors $\mathbf{N}_{1}$ and $\mathbf{N}_{2},$ respectively. If $\mathbf{N}_{1} \times \mathbf{N}_{2}=\mathbf{0},$ the planes are parallel.
