PLEASE HELP WILL RATE THE BRAINLIEST 1.He makes the following table to prove that the alternate interior angles are equal:

Statement Justification
angle 2 = angle 6 ?
angle 2 = angle 4 Vertical angles are congruent.
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? (6 points)

Group of answer choices

Co-exterior angles formed by a transversal on parallel lines are congruent.

Corresponding angles formed by a transversal on parallel lines are congruent.

Co-interior angles formed by a transversal on parallel lines are congruent.

Corresponding angles formed by a transversal on parallel lines are supplementary.

2.The sum of angle 1 and angle 4 and the sum of angle 3 and angle 4 are each equal to 180 degrees by the definition of supplementary angles. The sum of angle 1 and angle 4 is equal to the sum of angle 3 and angle 4 by the transitive property of equality. Angle 1 is equal to angle 3 .

Which phrase completes the proof? (6 points)

Group of answer choices

by construction using a straightedge

by the subtraction property of equality

by the definition of a perpendicular bisector

by the vertical angles theorem

3.Joel's proof: angle 2 + angle 3=180° (t is a straight line)
angle 1 + angle 2 = 180° (PQ is a straight line)
Therefore, angle 1 + angle 2 = angle 2 + angle 3 (Transitive Property of Equality)
Hence, angle 1 = angle 3 (Subtraction Property of Equality)

Melinda's proof: angle 1 + angle 2 + angle 3 + angle 4 = 360°
Therefore, angle 1 + angle 4 = 180° (t is a straight line)
Hence, angle 4 = angle 2 (Transitive Property of Equality)
