 \underline{ \LARGE \textsf{ \textbf{ \red{Required Solution}}}}

As we know in a square every angle is equal to 90°.

Now in ∆ACD,

 \textsf { \textbf{AD = CD (all sides of a square are equal)}}

We know angle opposite to equal sides are equal so

We know sum of all angles of a triangle is equal to 180°

 \angle \textsf{ \textbf{1= }} \angle \textsf{ \textbf{2=x (say)}}

 \sf \angle1+\angle2+\angle D = 180° \\  \sf x+x+90\degree=180 \degree\\  \sf 2x=90\degree \\   \boxed{ \red{\sf x= 45\degree}} \\

 \sf So, ∠1 = ∠2 = 45 \degree\\  \sf∠1 = ∠DAC =∠DCA = 45 \degree

Therefore, angle DAC = 45°
