CB Bisects \( ∢\text{ABD} \).
\( ∢ACD=\text{?} \)
ABCD is a square.
Due to the fact that all angles in a square are equal to 90 degrees, and BC bisects an angle, we can calculate angle ABC accordingly:
45
ABCD is a deltoid.
As we know that ABCD is a deltoid, and AC is the bisector of an angle and therefore:
Now we focus on the triangle BAD and calculate the sum of the angles since we know that the sum of the angles in a triangle is 180 degrees:
We divide the two sections by 6:
Now we can calculate the angle DAC:
