Remember that
If two angles are a linear pair, then their sum is equal to 180 degrees (supplementary angles)
so
Verify each statement
N 1 ----> False (not necessary, only in the case that each angle measures 90 degrees)
N 2 ---> is correct (definition of a linear pair of angles)
N 3 ---> is correct (a pair of linear pairs form a straight line)
N 4 --> is false (their sum is 180 degrees)
N 5 ---> is false (linear pairs are supplementary angles)
N 6
the statement is "If The converse is " If the angles are supplementary, then The converse is true
therefore
N 6 -----> is false
N 7 ----> is correct (JL and JK are opposite rays)
N 8 ---> is correct (the converse is true)
N 9 ---> is false (not necessary, only in the case that each angle measures 90 degrees)
