What are the undefined notions?
Option #1: point, line, distance along a line, and distance around a circular arc
Option #2: arc, parallel lines, perpendicular lines, and angle
Option #3: distance along a line, distance around a circular arc, angle, and arc
Option #4: line segment, angle, point, and arc
(1 point)
The undefined notions are Option #
.
Option #2
What is the precise definition of the figure in the image?
Option #1: two lines that intersects at a 90-degree angle
Option #2: two lines that never intersect and are the same distance apart
Option #3: two lines that intersect at a vertex point
The undefined notions are Option #2: arc, parallel lines, perpendicular lines, and angle.
To determine the correct option for the undefined notions, we need to analyze each option:
Option #1: point, line, distance along a line, and distance around a circular arc
Option #2: arc, parallel lines, perpendicular lines, and angle
Option #3: distance along a line, distance around a circular arc, angle, and arc
Option #4: line segment, angle, point, and arc
Upon reviewing the options, we can see that Option 2 contains undefined notions that are commonly used in geometry. These undefined notions are arc, parallel lines, perpendicular lines, and angle. Therefore, the correct answer is Option #2.
