A triangle with all three angles less than a right angle is called an acute triangle. To determine the type of triangle based on its angles, you need to know the measurements of the angles.

To classify a triangle as an acute triangle, you must check that all three angles are less than 90 degrees. Here's how you can determine if a triangle is acute:

1. Measure the three angles of the triangle using a protractor or by knowing the given values.
2. Check if each angle is less than 90 degrees.
3. If all three angles are less than 90 degrees, then the triangle is an acute triangle.

Remember, the sum of the angles in any triangle is always 180 degrees. So, if all three angles are less than 90 degrees, it means they add up to less than 180 degrees.

For example, if you know that the three angles of a triangle are 60 degrees, 70 degrees, and 50 degrees, you can determine that it is an acute triangle because each angle is less than 90 degrees.
