Exploring Lines, Rays, and Angles in Geometry

What defines a line in geometry?

• A collection of points that extends infinitely in one direction

• A set of points that extends infinitely in two directions

• A segment connecting two points

• A path that curves at one point

How is a ray different from a line?

• A ray connects two specific points

• A ray does not extend infinitely

• A ray has a definite starting point but extends infinitely in one direction

• A ray extends infinitely in two directions

Why can't the length of a line be measured?

• All of the above

• Because it does not have defined endpoints

• Because it extends infinitely in two directions

• Because it changes with perspective

What is the vertex of an angle?

• The point opposite the right angle

• The common endpoint of two rays

• The longest side of the angle

• The point where two lines meet

What is the measure of an angle primarily based on?

• The distance between the vertex and one point

• The length of the sides of the angle

• The amount of rotation needed to align one ray with another

• The number of degrees in a circle
