Can a triangle with two angles of 40 degrees and 60 degrees be obtuse?

In order to answer the question posed, you need to know that:

1. The sum of the angles of a triangle is 180 °.

2. Obtuse triangles are called when one of the angles is greater than 90 °.

If the two angles of a triangle are 40 °, then: 180 ° – 40 ° – 40 ° = 100 °

So the triangle is obtuse, since 100 °> 90 °.

If the two angles of a triangle are 60 °, then: 180 ° – 60 ° – 60 ° = 60 °.

This means that the triangle is acute-angled, in addition, all its angles are equal to each other and it can be called conformal.
