100
Identify the type of geometric element, then name it using geometric notation.
What is: Point; P
100
A point (or set of points) that elements have in common
Intersection
100
An angle is formed by two rays with a common endpoint also known as a ________.
What is: Vertex
100
True or False: This is the Segment Addition Postulate

200
Points that lie on the same line
Points that lie on the same plane
What is: Collinear and Coplanar
200
Identify the type of geometric element, then name it using geometric notation.
What is: Line Segment;
bar (TS) or bar (ST)
200
Determine whether the pair of given elements intersect, and if so, name the intersecting point for the identified elements.

What is: Yes; A
200
True or False: We can always name angles with 3 letters (vertex in the middle), 1 letter (the vertex), and 1 number.
False
We can angle angles:
1. With 3 letters and the middle letter being the vertex
2. With 1 letter (the vertex) when there are no other angles sharing the vertex
3. With 1 number if a number is in the diagram
