Answer:
29) RD≅RS
30) KL≅YZ
Step-by-step explanation:
29) SSS means three sides must be congruent. Already sides TD and TS are marked congruent, and we know side TR is congruent to itself by the reflexive property. The third sides, RD and RS must be congruent if you're to use SSS.
__
30) HL means "hypotenuse, leg". The legs KJ and YX are already shown as congruent, so the hypotenuses KL and YZ must be congruent if you're to use HL.
