Final answer:
The congruent triangles STR and RAS have six corresponding congruent parts: three pairs of congruent angles and three pairs of congruent sides, as indicated by their alignment in the congruence statement.
Step-by-step explanation:
The phrase STR = RAS likely refers to two congruent triangles, where triangle STR is congruent to triangle RAS. In congruent triangles, all corresponding sides and angles are congruent. Therefore, the six pairs of corresponding congruent parts are as follows:
- Angle S is congruent to Angle R (since they are in the same position in the notation).
- Angle T is congruent to Angle A.
- Angle R in triangle STR is congruent to Angle S in triangle RAS.
- Side ST is congruent to side RA.
- Side TR is congruent to side AS.
- Side RS in triangle STR is congruent to side AR in triangle RAS.
Remember that when writing congruencies in triangles, the order of the letters in the triangle names matters and corresponds to specific sides and angles.
