What is an obtuse triangle

The video tutorial explains the concept of obtuse angles, particularly in the context of triangles. It highlights that an obtuse angle is greater than 90 degrees and that a triangle can only have one obtuse angle since the sum of all angles in a triangle is 180 degrees. The teacher engages a student, Josh, to reinforce the understanding of these concepts through questioning. The session concludes with a reminder for students to take notes.
