Step-by-step explanation:

Use the identity

on the left side.
![\dfrac{1 - \cos [2(\frac{\pi}{4} - \alpha)]}{2} = \frac{1}{2}(1 - \sin 2\alpha)](https://tex.z-dn.net/?f=%20%5Cdfrac%7B1%20-%20%5Ccos%20%5B2%28%5Cfrac%7B%5Cpi%7D%7B4%7D%20-%20%5Calpha%29%5D%7D%7B2%7D%20%3D%20%5Cfrac%7B1%7D%7B2%7D%281%20-%20%5Csin%202%5Calpha%29%20)

Now use the identity

on the left side.


Answer:
Step-by-step explanation:
From the given figure, from ΔQRS and ΔTUV, we have
∠Q=∠T(56°(given))
∠R=∠U(83°(given))
∠S=∠V(41°(given))
Thus, by AAA similarity of triangles, ΔQRS is similar to ΔTUV.
Also, All the three angles made by both triangles are equal, and also they are similar thus they have same shape.
Thus, option C and D are correct.
