question
Which is the correct label of the parallel lines?
(not) A||B
question
James defines a circle as "the set of all the points equidistant from a given point." His statement is not precise enough because he should specify that
the set of points is in a plane
question
Which of the following is a flat surface that extends infinitely, has length and width, but does not have depth?
Plane
question
Anna draws an angle in her notebook. In how many points do the rays intersect?
1
question
Is the image an example of perpendicular lines?
Yes; the lines intersect at a right angle.
question
Statement: If two distinct planes intersect, then their intersection is a line. Which geometry term does the statement represent?
Postulate
question
Which term best describes the geometric figure?
Point
question
A line is an undefined term because it
(not) contains an infinite number of points
question
Which of the following is not a characteristic of a line?
Two endpoints
question
Which undefined terms are needed to define a line segment?
Point, line
question
Is the image an example of an angle? (Angle ABC- 65°)
Yes; AB and BC do not form a line and share an endpoint.
question
Which is the correct label of the line? (Line a, points C and D on line)
Line CD
question
Statement: If two points are given, then exactly one line can be drawn through those two points. Which geometry term does the statement represent?
Postulate
question
Which term best describes the geometric figure? (Segment AB)
Segment
question
A plane is an undefined term because it
is described generally, not using a formal definition
question
James defines a line segment as "a portion of a line." His statement is not precise enough because he should specify that
the segment has two endpoints
question
Statement: If two noncollinear rays join at a common endpoint, then an angle is created. Which geometry term does the statement represent?
Defined term
question
Which is the correct label for the angle?
∠CBA
question
Which undefined term is needed to define a circle?
Point
question
A ray is a defined term because it
