Question

unit 1 quiz 1
geometry a / unit 1 - the basics of geometry

1. choose true or false.

points that lie on the same plane are collinear.
true
false

1. choose the best answer.

which choice names a line segment?
ac
ab
bc
ab

Explanation:

Question 3:

Step1: Recall definitions

Collinear points lie on the same line. Coplanar points lie on the same plane.

Step2: Compare with statement

The statement says points on the same plane (coplanar) are collinear. But coplanar doesn't imply collinear.

Question 4:

Step1: Recall line - segment notation

A line segment is denoted by two endpoints with no arrow. A line has a ↔ over it (e.g., \(\overleftrightarrow{AC}\)), a ray has a → over it (e.g., \(\overrightarrow{BC}\)), and \(\overline{AB}\) is a line - segment.

Answer:

1. False
2. \(\overline{AB}\) (assuming the option with the line - segment notation is \(AB\) without arrows as per standard geometric notation)
