Answer:
The correct option is 2.
Step-by-step explanation:
Given information: ABCD is a parallelogram, AB║DC, BC║AD.
It is given that segment AB is extended and place point P above point B and segment AD is extended and place point T to the left of point A.
Alternate Interior Angles Theorem: If a transversal line intersect two parallel lines then alternate interior angles are congruent.
[tex]\angle 1\cong \angle 2[/tex] (Alternate Interior Angles Theorem)
[tex]\angle BCD\cong \angle PBC[/tex] (Alternate Interior Angles Theorem)
The values of blank 1 is "BCD and PBC".
Corresponding Angles Theorem: If a transversal line intersect two parallel lines then corresponding angles are congruent.
[tex]\angle 1\cong \angle 3[/tex] (Corresponding Angles Theorem)
[tex]\angle PBC\cong \angle BAD[/tex] (Corresponding Angles Theorem)
The values of blank 2 is "PBC and BAD".
Using Transitive Property of Equality,
[tex]\angle BCD\cong \angle BAD[/tex]
Similarly,
[tex]\angle ABC\cong \angle BAT[/tex] (Alternate Interior Angles Theorem)
[tex]\angle BAT\cong \angle CDA[/tex] (Corresponding Angles Theorem)
Using Transitive Property of Equality,
[tex]\angle ABC\cong \angle CDA[/tex]
Consequently, opposite angles of parallelogram ABCD are congruent.
Therefore the correct option is 2.
