Question

a student says that it is actually impossible to measure an angle, since each angle is the union of two rays that extend infinitely and therefore continue forever. what is your response? select the correct choice below. a. the student is incorrect. although infinite objects like angles, lines, and rays cannot be measured by physical devices, knowing that their size is infinite is a valid measurement of their size. b. the student is correct. in geometry, only objects with finite sizes like line - segments and triangles can be measured. c. the student is incorrect. angle measurements do not relate to length. angles are measured by the amount of opening between their sides. d. the student is incorrect. an angle measurement is a count of the number of rays between the sides of the angle that share the same origin. although there is no absolute maximum, this count is finite for any given angle.

Explanation:

Angles are measured by the amount of "opening" between their sides, not by the length of the rays which are infinite. So the student's claim that it's impossible to measure an angle because rays are infinite is incorrect.

Answer:

C. The student is incorrect. Angle measurements do not relate to length. Angles are measured by the amount of "opening" between their sides.
