• studied by abraham lincoln
• built an axiomatic system of geometry
  • based on axioms- statements accepted as
  true

Question 2

point

Answer 2

describes a location, zero dimensions

Question 3

line

Answer 3

• a collection of points along a straight path with no endpoints
• one dimension

Question 4

plane

Answer 4

• a flat surface that extends indefinitely

- two dimensions

Question 5

ray

Answer 5

• a collection of points along a straight path with one endpoint which extends indefinitely in one direction
• one dimension

Question 6

line segment

Answer 6

• a collection of points along a straight path with two endpoint
• one dimension

Question 7

angle

Answer 7

two rays that meet at a point

Question 8

why will two points always be collinear? why will three points always be coplanar?

Answer 8

1. two points will always be collinear because 2 points are needed to make a line
2. three points will always be coplanar because a plane can run through all three points
