Question

use the figure below to answer the following questions.
name three points coplanar with point a.
e, f, g
b, c, f
b, c, e
b, d, g

Explanation:

To determine coplanar points with \( A \), we analyze the figure. Point \( A \) lies on plane \( \mathcal{P} \). Points \( B \), \( C \), and \( E \) also lie on plane \( \mathcal{P} \) (since \( E \) is on the plane's edge, \( B \) and \( C \) are on lines within \( \mathcal{P} \)). Other options: \( E,F,G \) are colinear but not all on \( \mathcal{P} \); \( B,C,F \): \( F \) is outside \( \mathcal{P} \); \( B,D,G \): \( G \) is outside \( \mathcal{P} \). So \( B,C,E \) are coplanar with \( A \).

Answer:

C. B, C, E
