If all three angles are less than 90 degrees, then it is called an Acute Triangle.
If two angles are less than 90 degrees and the other one is 90 degrees, then it is called a Right Triangle.
If one angle is more than 90 degrees and the other two are less than 90 degrees, then it is called an Obtuse Triangle.

What type of triangle has an angle that measures less than 90 degrees?
acute
Does a triangle with 20 degrees 30 degrees and 130 degrees an acute triangle?
No. An acute triangle only has angles less than 90 degrees. A triangle with a 130 degree angle is obtuse.
What is an example of an acute angle?
An example of an acute angle is an acute triangle which is less than 90 degrees
What triangle has a right angle and 2 acute angles?
an isocelesANS2:Any triangle that has one right angle will have 2 acute angles. An acute angle is less than 90 degrees and the sum of all angles in a triangle is 180 degrees. The sum of the other two angles would have to add to 90 degrees so they would both have to be less than 90 degrees.
In the triangle the angle at a is 40 degrees less than the angle at b and 20 degrees less than the angle at c what is the size of each angle?
if the angle at a equals X then the angle at b equals X+40 and the angle at c equals X+20 the sum of the angels in a triangle is 360 degrees so: X + X+40 + X+20 = 360 3X + 60 = 360 3X = 300 X = 100.
What is isosceles triangle degrees?
The two equal angles can be any angle less than 90 degrees, and the third angle can be any angle less than 180 degrees.
What is the meaning of acute angled triangle?
An acute angled triangle means all the angles are less than 90 degrees because an acute angle is an angle less than 90 degrees.
How is an acute triangle different from both an obtuse triangle and a right triangle?
An acute triangle has no angle of 90 degrees or more. A right triangle has one angle of 90 degrees; the other two are less than 90 degrees. An obtuse triangle has one angle between 90° and 180°; the other two are less than 90°.
A triangle that has one angle greater than 90 degrees?
this is called an obtuse triangle the triangle that has one angle 90 degrees is called a right traingle a triangle that has 3 angles less than 90 degrees is called an acute triangle
A right angle triangle has one angle of 90?
Yes.The definition of every triangle-Right triangle---A triangle that has one right angle(90 degrees).-Obtuse triangle---A triangle that has one obtuse angle(greater than 90 degrees).-Acute triangle---A triangle that has all acute angles(less than 90 degrees).
What degree angle is an acute triangle?
An acute angle is any angle less than 90 degrees.
An acute triangle is a triangle that has what?
an angle less than 90 degrees but more than 0 degrees.So basically, a triangle 89-1 degrees is an acute triangle.
What is the meaning of acute angle?
An acute angled triangle means all the angles are less than 90 degrees because an acute angle is an angle less than 90 degrees.
Is a right angle triangle acute or obtuse?
Neither. An acute triangle has all angles less than 90 degrees. An obtuse triangle has one angle more than 90 degrees. A right triangle is simply just a right triangle, since it has one angle of 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.
The smallest angle in a triangle measures 90 degrees less than the largest angle The middle angle measures 60 degrees less than the largest angle?
The angles are, 20°, 50°, and 110°.
Can a angle of a triangle can be less than 60 degree?
Yes. An angle of a triangle can be any number greater than 0 and less than 90 in degrees.
