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.
