Lesson 1 Vocab Flashcards
Drawn as a dot
A single capital letter
A location that has no size and no dimensions
point
An arrow on both ends
Any two points on this
A lowercase letter, notation order doesn’t matter
An infinite number of points on a straight path, one dimensional
line
a slanted 4 sided figure
3 points in this, non collinear
Notation order doesn’t matter
An infinite number of points and lines on a flat surface, two dimensional
plane
points on the same line
collinear
points not on the same line
non-collinear
through any two points, there is exactly one line
unique line postulate
objects that are on the same plane
coplanar
through any three noncollinear points, there is exactly one plane
unique plane postulate
Two distinct lines intersect, then they intersect at exactly one …
point
If two planes intersect, then their intersection is at a ..
line
If a plane and a line intersect, they intersect at one …
point
A dot with both ends.
Named by its ends points but order doesn’t matter.
The part of a line that consists of two points.
segment
A dot on the end with an arrow on the other.
End point first and then another point on the line.
The part of the line that consists of one endpoint.
ray
A common endpoint with an arrow on both sides.
The common endpoint and another point on each line.
opposite rays
two rays with a common endpoint (vertex)
for notation the vertex must be in the middle when labeling with 3 points.
angles
