Question

write the name of opposite angle of < pts

ans : < rtq.​

Answer 1

Step-by-step explanation:

ans-rtq

Answer 2

Step-by-step explanation:

In ΔRTS, we have

RT=ST

⇒∠TSR=∠TRS (i)

We have,

∠1=∠4  [Vertically opposite angles]

⇒2∠2=2∠3 [∵∠1=2∠2 and ∠4=2∠3 (given)]

⇒∠2=∠3 (ii)

Subtracting (ii) from (i), we get

∠TRS−∠2=∠TSR−∠3

⇒∠TRB=∠TSA (iii)

Thus, in triangles, RBT and SAT, we have

∠RTB=∠STA [Common]

RT=ST  [Given]

and, ∠TRB=∠TSA [From (iii)]

So, by ASA congruence criterion, we obtain

ΔRBT≅ΔSAT
