ANSWER
Reflexive property
Alternate interior angles are equal
AAS
Explanation:
Looking at the figure given
0. Length TS is parallel to the length RQ
,
1. Length TQ is parallel to the length RS
For triangle RSQ to be equal to triangle TQS
We need to know the following theorem
• Reflexive property
,
• Alternate interior angles are equal
Secondly, the theorem is
AAS - Angle-Angle-Side because we can prove two pairs of alternate angles are equal from the diagram
