A triangle is acute if it is less than 90 degrees. It is obtuse if more than 90 degrees
If you only know one angle, that angle is greater than 90 degrees, then the triangle is obtuse If that angles is equal to 90 degrees, then the triangle is a right triangle. If it is less than 90 degrees, you don't know enough information to classify the triangle.
you know a triangle is obtuse when it is larger than a right angle which is 90 degrees. ex. a clock when it is 12:15 it makes a right angle or 90 degrees.
A right angles triangle, as one of the angles in the triangle is 90 degrees.
You know it's an obtuse triangle when one of the angles is greater than 90 degress, and both of the others are less than 90 degrees.

Any triangle with a 90 degree angle is called a right triangle.
A right angles triangle, as one of the angles in the triangle is 90 degrees.
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
You know it's an obtuse triangle when one of the angles is greater than 90 degress, and both of the others are less than 90 degrees.
The question "What are the classifications of a triangle" is answered elsewhere. The angles in a triangle can be either an obtuse >90 degrees, an acute <90 degrees, or a rectal = 90 degrees
It has 180 degrees, but one angle of the triangle has to be 90 degrees
A triangle with one angle over 90 degrees is an obtuse triangle.
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees
Acute Triangle - All of the angles are under 90 degrees. Right Triangle - One angle is 90 degrees Obtuse Triangle - A triangle that has one angle greater than 90 degrees.
