Question

State the type of the following triangle:

Triangle $PQR$, Angle P $=40$°, Angle Q $=60$°, Angle R $=80$°.

Answer 1

Finding the type of the triangle:

If we observe the angles of the given triangle:

Angle P $=40$°, Angle Q $=60$°, Angle R $=80$

We can say that all the angles are less than 90°. That is, all the angles are acute angles.

Also, an acute-angled triangle is a triangle in which all the angles are acute angles.

Hence, the given triangle $PQR$ is an Acute-angled triangle.
