Part a: an angle is two collinear rays with a common endpoint. find an example that contradicts this definition. how would you change the definition to make it more accurate?

part b: give an example of an undefined term and how it pertains to angles.

i believe the answer is the polygon, heptagon.

idk

step-by-step explanation:

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5

happy to
