AB turns clockwise to coincide with BC.

To find the angle by which turns counterclockwise to coincide with is 243.9 degrees:

An angle -

An angle is a figure in Euclidean geometry created by two rays, called the sides of the angle, that share a common termination, called the vertex of the angle.
Angles formed by two rays are located in the plane containing the rays.
Angles are also generated when two planes intersect.
These are known as dihedral angles.

So,

= ABD + DBC

= 33.3° + 30.6°

= 63.9°

b) If E is drawn directly opposite C.

EBC is a straight line, so the sum of angles =180°

ABE + ABD + DBC = 180°

ABE + 33.3° + 30.6° = 180°

ABE + 63.9° = 180°

ABE = 180 - 63.1

ABE = 116.9

Therefore, AB turns clockwise to coincide with BC.
