Question

in the following figure ST=SU and SR | TU prove that ∆STR = ∆SUR
​

Answer 1

Answer:

If it helps mark me as brainliest.

Step-by-step explanation:

In ∆STR and ∆SUR,

angle SRT= angle SRU=90°

SR=SR

ST=SU

So, the triangles are congruent. [RHS rule]

Answer 2

Step-by-step explanation:

ST = SU (GIVEN) (If the opposite sides are equal then the angle is isosceles)

<T = <U (Isosceles triangle rule)

TR = UR (As SR | TU)

Thus, ∆STR = ∆SUR (SAS Congruency rule)

Hope it helps!
