To show that triangle trk= triangle tuk by the sas postulate, what additional information is necessary?

a. b. tk=tk
c. d.

From the figure, we already have
RT = UT
and
TK = TK

Since these are already conditions for two sides being congruent, we only need an included angle to be congruent. So, the missing information is 
∠RTK ≅ ∠UTK

Find the perimeter of the figure shown above with a side length 5 units.(each figure is a square).a.10 unitsc.30 unitsb.20 unitsd.40 units select the best answer from the choices providedabcdmark this and return

Ithink the answer is discovery verbs because they are quite similar to the verb 'discovering'
