Explain how many acute and obtuse angles are created when 2 parallel lines are crossed by a single transversal that is not perpendicular to them. Create pictures to help. Identify how many unique acute angle measures there are and how many unique obtuse angle measures there are, explain your reasoning. Propose a generalization for when there are no parallel lines, and confirm the generalization matches what was found for the cases of 2 parallel lines. Prove the generalization, explaining all of your reasoning

Going from point a to point b, the cheetah traveled at an average rate of 70 mph. returning to point a, the cheetah traveled at an average rate of 40 mph. can we say that this cheetah’s average rate was 55 mph? uchet write an equation for the average rate for the trip. remember, the cheetah runs from point a to point b and back to point a. first leg of trip: second leg of trip: ⦁ the following equation represents the average rate for the trip. is this equation equivalent to the one you wrote above? explain why or why not.
