The given statement "The exterior angles of a triangle are always obtuse." is not always true.
The given statement is "The exterior angles of a triangle are always obtuse."
We need to provide a counterexample to the given statement.
The angle is formed by a polygonalside and its extended neighbouring side. When a transversal cuts one of two lines, it creates an angle that is outside of the line.
Take an obtuse-angled triangle as a counter-example:
An obtuse-angled triangle or obtuse triangle is a type of triangle whose one of the vertex angles is bigger than 90°. An obtuse-angled triangle has one of its vertex angles as obtuse and other angles as acute angles i.e. if one of the angles measure more than 90°, then the sum of the other two angles is less than 90°.
In the figure given below, we can see in ΔABC, ∠A=110°.
Exterior angle to ∠A measures 70°.
Therefore, the given statement "The exterior angles of a triangle are always obtuse." is not always true.
