Triangles: https://vallejocity.owschools.com/media/g_geo_ccss_2016/4/img_geou04l04_03.gif
explain what additional information is needed to prove triangle CES congruent to triangle RST.

You can put this solution on YOUR website!
The two triangles are similar, because they are right triangles, and angles CSE and RST are congruent because they are vertical angles.
To prove congruence, you need any one pair of corresponding sides to be congruent.
It could be any one of CS and RS, or CE and RT, or ES and TS.
