Question

can you match the teachers comments to the definitions?
definition of an angle
rubys definition: the amount of turn between two straight lines that have a common vertex.
shriyas definition: two lines that come together.
abhisheks definition: a figure composed of two rays sharing a common endpoint. the common endpoint is known as the vertex.
teachers comments
bingo! youve got it!
were you thinking of intersecting lines?
you seem to be getting at the idea of the measure of an angle, not the definition of the angle itself.

Explanation:

Ruby's definition is correct for an angle, so the teacher's comment "Bingo! You've got it!" matches it. Shriya's definition is too general as two lines coming together could refer to intersecting lines, so the comment "Were you thinking of intersecting lines?" is appropriate. Abhishek's definition focuses more on the measure - related idea rather than the basic definition of an angle, so the comment "You seem to be getting at the idea of the measure of an angle, not the definition of the angle itself." fits.

Answer:

Ruby's definition - Bingo! You've got it!
Shriya's definition - Were you thinking of intersecting lines?
Abhishek's definition - You seem to be getting at the idea of the measure of an angle, not the definition of the angle itself.
