Question

(01.01 lc)
statement: if two noncollinear rays join at a common endpoint, then an angle is created. which geometry term does the statement represent?
o a defined term
o b postulate
o c theorem
o d undefined term

question 9 (1 points)
(01.01 mc)
which of the following is not a characteristic of a plane?
o a flat surface
o b length and width
o c two endpoints
o d undefined term

Explanation:

• For the first question:
• A defined term is a term that has a formal definition. An angle is defined as two non - collinear rays joining at a common endpoint.
• A postulate is a statement that is assumed to be true without proof.
• A theorem is a statement that can be proven.
• An undefined term is a term like point, line, or plane that is not formally defined in geometry (but is described).
• For the second question:
• A plane is a flat surface (a characteristic).
• A plane has length and width (it is a two - dimensional figure, so these are characteristics).
• A plane extends infinitely in all directions and does not have two endpoints.
• A plane is an undefined term in geometry (a characteristic in the sense of how it is classified in the geometric system).

Answer:

• First question: a. Defined term
• Second question: c. Two endpoints
