By which angle must turn about point A in the clockwise direction so that it coincides with ? https://cdn. ple. platoweb. com/EdAssets/6168ddce5d8545b692cd00 c2eaaf2f05?ts=635385675311870000

A. 90°
B. 180°
C. 270°
D. 360°

When a line is rotated, it is rotated about a fixed point to its new position. Line AB must turn 180 degrees about point A to coincide with line AE.

The complete question is that we determine the angle which AB will turn to, about point A to align with AE (see attachment for the figure)

Line AB and AE form a straight line. This means that the angle between these two lines on either side of point A is

So for line AB to coincides with line AE, the line AB must turn 180 degrees about point A.

Hence, option (B) is correct.
