Question

choose the best option to fill in the blank for the following statement: the three undefined terms in geometry are point, ______, and plane. options: median, line, altitude, trapezoid. skill code: 1634001

Explanation:

In geometry, the three undefined terms are point, line, and plane. Median is related to triangles (a line segment), altitude is a perpendicular segment in a triangle, and trapezoid is a type of quadrilateral—all of these are defined terms, not undefined. So the correct option is "line".

Answer:

B. line (assuming the second option is labeled B, with the text "line")
