Answer:
The coordinates of end points of the side congruent to JM i.e J'M' are J'(-2,-6) & M'(-1,5).
Step-by-step explanation:
Given the coordinates of parallelogram JKLM
J(-6,2) , K(-4,6), L(-3,3), M(-5,-1)
Now, the parallelogram JKLM is rotated 270° clockwise around the origin, then the coordinates after rotation about 270° changes to
(x,y) → (y,-x)
Hence, the coordinates of the endpoints of the side congruent to side JM are
J(-6,2) → J'(-2,-6)
M(-5,-1) → M'(-1,5)

Answer:
Distinct ways in which they all can form the teams for the class = n(n-1)
Step-by-step explanation:
Total numbers of students = n (even number)
Number of student in each team = 2
Number of distinct ways are there to form the teams for the class:
where = n = number of elements = n
k = number of elements choose = 2
