Jazz draws a transversal, t, on two parallel lines ab and cd, as shown below:

(first pic)

he makes the following table to prove that the alternate interior angles are equal:

statement justification
angle 2 = angle 6 corresponding angles of parallel lines are congruent.

angle 2 = angle 4 ?

angle 4 = angle 6 transitive property of equality,
angle 2 = angle 6,
angle 2 = angle 4,
therefore angle 4 = angle 6

which is the missing justification?

angles 1 and 3 are supplementary; therefore, angle 2 is equal to angle 4.
alternate interior angles are congruent.
vertical angles are congruent.
angles 1 and 4 and angles 1 and 2 are congruent; therefore, angle 2 is equal to angle 4.

Vertical angles are congruent.

Step-by-step explanation:

Vertical angles are opposite angles that share only a vertex.  ∠2 and ∠4 are opposite angles that share only a vertex; this makes them opposite angles.  

Vertical angles are congruent; this means that ∠2 and ∠4 are congruent.

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
