Question

Students in Ms. Bell’s geometry class created posters of geometric definitions. Which of the following is the most precise definition?
A. Parallel lines are lines that do not intersect.

B. A line segment is part of a line that has an endpoint.

C. Perpendicular lines are lines that intersect at a right angle.

D. An angle is formed by two lines, two segments or two rays in one plane.

Answer 1

Answer:

C

Step-by-step explanation:

D is missing 2 ideas.

• An angle can be formed by a mixture of the types of figures quoted.
• An angle has common or shared endpoint.

B: to me is unclear. A line does not have an endpoint. A ray does.

A: you need to mention that the lines are coplanar.

I think, brief though it is, C is the most complete and at the same time simplest choice.
