If some knows plz help me

See explanation

Step-by-step explanation:

5) Yes. Yes. The two triangles share side WV, meaning that side is the same length on both triangles. VS and VU are also the same length on the respective triangles. They also both have on 90 degree angle. By SAS, they are congruent.

6) Yes. The two triangles share side TV, meaning that side is the same length on both triangles. VS and VU are also the same length on the respective triangles. They also both have on 90 degree angle. By SAS, they are congruent.

7) Yes. Since triangles WVS and WVU are congruent, sides WS and WU are congruent. Since the triangles share side TW, TW is congruent on both triangles. Since triangles TVS and TVU are congruent, sides TU and TS are congruent on both triangles as well. TWS and TWU are congruent by SSS.
