What is the next step in the proof? choose the most logical approach.
a.
statement: 26* 214
reason: for parallel lines cut by a transversal, corresponding angles are congruent.
o b.
statement: 26 = 27
reason: vertical angles theorem
o
c.
statement: 26 and 25 are supplementary.
reason: linear pair theorem
d.
statement: m26 + m28 = 180°
reason: angle addition

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.
