Geometry Vocabulary

James and Kai are discussing whether a highway and a driveway have no differences.

• False

• True

Answer explanation

A line extends infinitely in both directions, while a line segment has two endpoints. Therefore, they are not the same, making the statement false.

Rohan and Emma are standing on a field. Rohan walks in a straight line from north to south, while Emma walks in a straight line from east to west. Their paths are perpendicular. Do their paths never intersect?

• True

• False

Answer explanation

The statement is false because perpendicular lines do intersect at a right angle. Therefore, they cannot be described as never intersecting.

Abigail and Kai are drawing on a piece of paper. Abigail draws a continuous straight extent of length, without breadth or thickness, which is called a ______________. It also has arrowheads on both sides.

• linear pair

• line segment

• line

• ray

Answer explanation

A continuous straight extent of length with no breadth or thickness is defined as a line. It is characterized by having arrowheads on both ends, indicating it extends infinitely in both directions.

Avery and Ethan are drawing a line on a piece of paper. The points that are at the ends of the line segment they draw are called ____________________.

• endpoints

• midpoints

• rays

• arrows

Answer explanation

The correct term for the points at the ends of a line segment is 'endpoints'. Midpoints refer to the center point, while rays and arrows are different geometric concepts.

Abigail, Daniel, and Jackson are arranging chairs in a hall. The chairs that lie in the same plane are called _______________.

• coplanar points

• defined terms

• collinear points

• line segment

Answer explanation

Points that lie in the same plane are referred to as coplanar points. This term specifically describes the relationship of points within a single flat surface, distinguishing them from collinear points, which lie on the same line.
