How do you know if a triangle is acute?
A triangle is acute if it is less than 90 degrees. It is obtuse if more than 90 degrees
How do you classify a triangle with only one angle?
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.
How do you know a triangle in an obtuse 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.
If the angles in a triangle are 30 degrees 60 degrees and 90 degrees is called what type of triangle is it?
A right angles triangle, as one of the angles in the triangle is 90 degrees.
What are the angle classifications of a triangle?
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

A triangle is acute if it is less than 90 degrees. It is obtuse if more than 90 degrees

What do you call A triangle with a 90 degrees angle?
Any triangle with a 90 degree angle is called a right triangle.
If the angles in a triangle are 30 degrees 60 degrees and 90 degrees is called what type of triangle is it?
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 what is the third angle?
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.
A right triangle is a triangle that has how degrees?
It has 180 degrees, but one angle of the triangle has to be 90 degrees
What are the angle classifications of a triangle?
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
A right triangle has 28 degrees angle what are the measures of the other angles?
The sum of the internal angles of a triangle is 180 degrees. Since you know this is a right-angled triangle, you know that one side is 90 degrees. If the other angle is 28 degrees, then you know that the remaining angle must be 180 - 90 - 28 = 62 degrees.
How do you know when its an obtuse triangle?
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.
A triangle with one angle over 90 degrees?
A triangle with one angle over 90 degrees is an obtuse triangle.
Kinds of triangle according to angles?
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
