Question
Show the conjecture is false by finding a counterexample.
Two supplementary angles form a linear pair.
The correct answer is: the given statement is false
Given, two supplementary angles always form a liner pair
We have to determine if the given statement is true or false.
When the sum of measures of two angles is 180 degrees, then the angles are called supplementary angles.
When two lines intersect each other at a single point, linear pairs of angles are formed.
From the figure,
∠1 + ∠2 = 180°
Linear pair of angles occurs in a straight line.
So, two supplementary angles do not always form a linear pair.
Therefore, the given statement is false.
