It is either symmetric property or transitive. In view of in the event that they need you to show that they are harmonious, or opposite balanced. For 2, edge b is reflexive in light of the fact that b=b, so the point itself is likewise symmetric.
For 1. It is either symmetric property or transitive. Based on if they want you to show that they are congruent, or perpendicular symmetrical. For 2, angle b is reflexive because b=b, so the angle itself is also symmetric. Do you have any other information for numbers 3 and 4? Or do they just want you to repeat the side angle side congruences.
