1. provide reasons for the statements.
given: ∠1 and ∠3 are vertical angles.
prove: ∠1 ≅ ∠3
statement reason
1. ∠1 and ∠3 are vertical angles. 1. given
2. ∠1 and ∠2 form a linear pair.
∠2 and ∠3 form a linear pair. 2. definition of linear pair
3. ∠1 and ∠2 are supplementary.
∠2 and ∠3 are supplementary. 3.
4. m∠1 + m∠2 = 180˚
m∠2 + m∠3 = 180˚ 4.
5. m∠1 + m∠2 = m∠2 + m∠3 5.
6. m∠1 = m∠3 6.
7. ∠1 ≅ ∠3 7. given
2. in the figure, point b is the midpoint of ac. use the figure to answer the questions.
(a) jeremy says that △abd ≅ △cbd by the sas congruence postulate. do you agree or disagree? explain.
(b) suppose it is also known that ad ≅ cd. which postulate or theorem can be used to prove that △abd ≅ △cbd? justify your answer.
3. use rigid motions to explain whether the triangles in the figure are congruent. be sure to describe specific rigid motions in your explanation.
the picture goes in the same order as the questions. the 1, 2, 3, 4 picture goes with question one, the upside down triangles goes with question 2 and the graph goes with question 3.
need don't know any of these, i need with these questions asap before 11: 59 p. m. you

Which scenarios are most effectively explored by conducting an experiment? there is more than one correct answer. select all that apply. researchers want to study the effectiveness of a particular drug for treating migraines. they want to know which dosage of the drug yields the best results with the least side effects. to ensure fair results, the researchers want to ensure that participants and dosage administrators do not know which dosage participants receive. a teacher wants to plan a class fieldtrip and quickly determine where students prefer to go for the class fieldtrip. a car mechanic wants to know which of two engine brands makes better-performing engines. he wants to test the engines in identical situations and rate their performance in a way that can be fairly measured. a chemist studies the properties of a metal compound. she wants to know how the sample size of the metal affects its ability to conduct electricity. she wants to conduct the research in a controlled environment to minimize bias. a realty company wants to know the average income of its clients. the company wants to gather data income from current clients.
