Name the type of triangle
$△ A B C$ with $∠ A = 40 °$ , $∠ B = 80 °$ and $∠ C = 60 °$

Solution

We know that, if a triangle consists of three acute angles is called acute angled triangle , or
It means that all the angles of the triangle are less than $90$ degrees.
Here ,we have $∠ A = 40 °$ , $∠ B = 80 °$ and $∠ C = 60 °$
As aAll the angles are less than $90$ $°$
Therefore, $△ A B C$ is acute angled triangle.
