the proof that δrst ≅ δvst is shown.

given: st is the perpendicular bisector of rv.
prove: δrst ≅ δvst

what is the missing reason in the proof?

Correct choice is A.

Step-by-step explanation:

The perpendicular bisector theorem states that if a point is on the perpendicular bisector of a segment, then it is equidistant from the segment's endpoints.

Point S is on the segment ST. ST is perpendicular bisector of RV. Points R and V are endpoints of the segment RV. Then by the perpendicular bisector theorem,

SR≅SV.

Correct choice is A.

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
