The answer is (SAS) Theorem. Because  we know triangle ERT is congruent to  triangle CTR, it has the sides ( C& E and R&T, and the angle T&R).

<u><em>Hope its correct.</em></u>

<span>Consider the triangles ERT and  CTR.

|ER|=|CT| shown

(</span>Therefore, one can say that segment ER is congruent to segment CT.)

m(R)=m(T)= 90°shown

(By the definition of a rectangle, all four angles measure 90°)

|RT|=|TR|

so we have Side Angle Side congruence.

By the <span>(SAS) Theorem, the triangles are congruent.


Answer: </span><span>C (SAS) Theorem</span>

a^2+ b^2= c^2 where a and b are the other two sides of the right angled triangle, hence c= square root (15^2+ 20^2)= 25
