Question

identify all points and line segments in the picture below. points: a, b, c, d line segments: ab, ad, ac, dc, bc

Explanation:

Step1: Identify points

The points in the figure are A, B, C, D.

Step2: Identify line - segments

A line - segment is a part of a line that is bounded by two distinct end - points. The line - segments are $\overline{AB}$, $\overline{AC}$, $\overline{AD}$, $\overline{BC}$, $\overline{BD}$, $\overline{CD}$, $\overline{DC}$, $\overline{CB}$, $\overline{DA}$, $\overline{CA}$, $\overline{BA}$. But considering non - redundant ones based on the naming convention where $\overline{AB}$ and $\overline{BA}$ represent the same line - segment, the line - segments are $\overline{AB}$, $\overline{AC}$, $\overline{AD}$, $\overline{BC}$, $\overline{BD}$, $\overline{CD}$, $\overline{DC}$, $\overline{CB}$, $\overline{DA}$, $\overline{CA}$, $\overline{BA}$.

Answer:

Points: A, B, C, D; Line segments: $\overline{AB}$, $\overline{AC}$, $\overline{AD}$, $\overline{BC}$, $\overline{BD}$, $\overline{CD}$, $\overline{DC}$, $\overline{CB}$, $\overline{DA}$, $\overline{CA}$, $\overline{BA}$
