Half of n, is option D, n/2.
This is because if you divide something by 2, you are dividing it in half.
Hope this helps!
All in all you would get the answer x+y=1.
Question 11:
Isometry is a transformation the preserves the distance and there is no change in the distances. It includes rotation, reflection and translation . Hence the figures are congruent. So the statement is false
Question 12:
A reflection is a transformation where every point of the line is of equal distance from a particular line called the line of reflection
Hence this statement is true
Question 13:
The angle of rotation is the turning of every angle of a figure about a specific fixed point in a specific degree. Hence the statement is true
