Line Segments
What is a line?
A one-dimensional, straight path that extends infinitely in both directions
A plane is determined by any two points.
False
What is distance?
Distance is the measurement of the length between two points
All roses are flowers. Some flowers fade quickly. Can we conclude that some roses fade quickly?
No, we cannot conclude that. The fact some flowers fade quickly doesn't necessarily include roses.
What is a right angle?
An angle that is congruent to 90 degrees.
What are endpoints?
The ends of a line segment.
What is a plane?
A fundamental, flat, two-dimensional surface that extends infinitely in all directions
What is the distance between (1, 2) and (4, 6)?
5 Units.

Yes, all whales have lungs.
What is an obtuse angle?
An angle that is more than 90 degrees
What is a ray?
