Exploring Lines, Line Segments, Rays, Angles, and Vertices

What defines a line in mathematical terms?

• A segment with two endpoints

• A path with one endpoint

• A curve that extends infinitely

• A straight path that is infinite on both ends

What is a line segment?

• A straight path with two specific endpoints

• A straight path without endpoints

• A curved line

• An infinite line

What is a ray in geometry?

• A line with no endpoints

• A line segment extended infinitely in one direction

• A segment with two endpoints

• A fully circular path

What forms a vertex?

• Two line segments meeting at a point

• Two rays meeting at a point

• A single line bending

• A line crossing itself

How is an angle formed?

• By a line segment dividing into two

• By the distance between two lines

• By two lines intersecting at any point

• By two rays originating from the same point

What is a 90-degree angle known as?

• Obtuse angle

• Right angle

• Acute angle

• Straight angle

What does a 180-degree angle represent?

• A full circle

• A quarter circle

• A half circle

• A third of a circle

What is the significance of the angle that is exactly 90 degrees?

• It represents a straight line

• It is called an obtuse angle

• It is known as a right angle

• It indicates a full rotation

How do you refer to an angle in a triangle with vertices labeled P, Q, R?

• Angle QRP

• Angle PRQ

• Any of the above as long as P is in the middle

• Angle RQP

Which angle is larger based on the description: angle ABC or another angle slightly larger than 90 degrees?

• Angle ABC

• The other angle

• Both are the same

• Cannot be determined
