How to classify a triangle by its angles?
Understand the Problem
The question asks how to classify triangles based on their angles. Triangles can be categorized into three main types based on their angles: acute, right, and obtuse triangles. An acute triangle has all angles less than 90 degrees, a right triangle has one angle exactly 90 degrees, and an obtuse triangle has one angle greater than 90 degrees.
Answer
Acute, Right, and Obtuse triangles.
There are three types of triangles based on their angles: acute, right, and obtuse. An acute triangle has all angles less than 90 degrees. A right triangle has one angle exactly 90 degrees. An obtuse triangle has one angle greater than 90 degrees.

More Information
Classifying triangles by their angles helps in understanding the properties and solving geometric problems involving triangles.
Tips
Common mistakes include misidentifying angles, like assuming an angle is right or obtuse when it is not perfectly 90 or more than 90 degrees.
