Question

Precisely define an angle.(1 point) Responses An angle is the figure formed by two lines extending from the same point. An angle is the figure formed by two lines extending from the same point. An angle is a closed plane curve with every point on the curve equidistant from a fixed point within the curve. An angle is a closed plane curve with every point on the curve equidistant from a fixed point within the curve. An angle is the finite section of a line between two endpoints on the line. An angle is the finite section of a line between two endpoints on the line. An angle is a line that extends forever in one direction for a single endpoint.
Answer
What makes a line parallel?(1 point) Responses A parallel line is a straight figure that has no thickness and extends infinitely in two opposite directions. A parallel line is a straight figure that has no thickness and extends infinitely in two opposite directions. A parallel line is a line that intersects another line at a 90-degree angle. A parallel line is a line that intersects another line at a 90-degree angle. A parallel line is the finite section of a line between two points on that line. A parallel line is the finite section of a line between two points on that line. A parallel line is a straight line that always remains the same distance from another line and never intersects it.

Answer
Postulates, definitions, conjectures, and theorems each have distinguishing features that help identify them. Which of the following answer choices accurately represents the term’s distinguishing feature? (1 point) Responses A conjecture tells you what a term means or what to do with a concept. A conjecture tells you what a term means or what to do with a concept. A postulate is assumed to be true, and it does not have to be proven. A postulate is assumed to be true, and it does not have to be proven. A theorem is assumed to be true, and it does not have to be proven. A theorem is assumed to be true, and it does not have to be proven. A definition is a statement that is made based on observations that must be proven true.
