Given: angle Q is congruent to angle T and line QR is congruent to line TR
Ainat [17]

3. <u>Two angles and included side (ASA congruence theorem)</u>.

<u>Reason:</u> This is because, it is given that angle Q is congruent to angle T and line QR is congruent to line TR. Also, we proved in step 2 that \angle PRQ\cong\angle SRT. Thus, we have two angles and the side included as congruent and thus, the two triangles are congruent.

4. <u>CSCT (Corresponding Sides of a Congruent Triangle)</u>

<u>Reason:</u> PR and SR are the corresponding sides of the congruent triangles \Delta PRQ and \Delta SRT, therefore, by the CSCT these corresponding sides have to be congruent.
