Me quick complete the proof of the exterior angle theorem. given: ∠4 is an exterior angle of △abc. prove: m∠1+m∠2=m∠4

Step-by-step explanation:

Statement                                                                        Reason

1.∠4 is an exterior angle of ΔABC                                  Given

2.∠3 and∠4 form a linear pair                                 Linear pair theorem

3.∠3 is supplementary to ∠4                        Property of supplementary angle

4.m∠3+m∠4=180°                                        Definition of supplementary angle

5.m∠1+m∠2+m∠3=180°                               Triangle sum theorem

6.m∠1+m∠2+m∠3=m∠3+m∠4                     From step 4 and 5

7.m∠1+m∠2=m∠4                                        Subtraction rule

step-by-step explanation:

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
