Dear Student,

Before turning 135 degree to his left, he was facing south-west direction. one quadrant measures 90 degree, so when he will trurn 135 degree to his left, first 45 degree will take him to south direction and then next 90 degree will take him to East direction. So, in total 135 degree rotation he will be facing eastward.

Hope you have a great learning with us!!

All the Best,
