how do I know weather it is true or false for the following statements?

Perpendicular lines are lines that meet at 90 degrees.
EH is not perpendicular to FG because both lines do not meet at right angles (90 degrees)
Therefore, EH ⟂ FG = False
Parallel lines are two lines that do not meet in the same plane
DH is parallel to FB because both lines cannot meet
DH // FB = True
Points are coplanar if they belong to the same plane
Points D, C, E anf F do not belong to the same plane, therefore they are not coplanar
Points D, C, E and F are coplanar = false
Points are colinear if they lie on the same line
Points A, C, and H do not lie on a single line, they are not colinear.
Points A, C, and H are colinear = False
