Question

1. which of the following statements can be assumed about the diagram below. points a, b and f are collinear. points e, b and d are collinear. ab ⊥ plane s. cd ⊥ plane t. af intersects bc

Explanation:

Step1: Check collinearity of points

Points A, B and F lie on the same line in plane T, so they are collinear. Points E, B and D do not lie on the same straight - line.

Step2: Check line - plane perpendicularity

There is no indication that $\overline{AB}\perp$ Plane S or $\overline{CD}\perp$ Plane T from the diagram.

Step3: Check line - line intersection

$\overline{AF}$ and $\overline{BC}$ are skew lines and do not intersect.

Answer:

Points A, B and F are collinear
