Answers
Given : two adjacent supplementary angles always lie on a straight line :
To Find : true or false
Solution:
Two angles are supplementary if their measures add up to 180°
two adjacent supplementary angles will add up to 180°
Hence will form a straight line
so two adjacent supplementary angles always lie on a straight line is TRUE
