If all three angles of a triangle measure less that 90 degrees (if all three angles are acute), the triangle is an acute triangle.

A triangle that has a right angle (an angle the measures exactly 90 degrees) is a right triangle. (The other 2 angles will be acute angles.)

A triangle that has an angle that is greater than 90 degrees (an obtuse angle), is an obtuse triangle. (The other 2 angles will be acute angles.)

What do you write when classifying triangles?

there is many ways to write when classifying a triangle, you can classify it by its sides or angles. When you classify it by angles you can classify it by acute, obtuse, and right triangle. when classyfing it by sides its isosceles, equilateral, and scalene!


Examples of how to classift a triangle in two ways?

You can classify a triangle by its sides or by its angles. I.e: A triangle with three equal sides is an equilateral triangle A triangle with three equal angles is an equiangular triangle A triangle with two equal sides is an isosceles triangle


Classify the triangle by its angles?

An acute angled triangle has all its angles less than 90°.A right angled triangle has one of its angles equal to 90°.An obtuse angled triangle has one angle greater than 90°.A scalene triangle has all three sides of different lengths.An isosceles triangle has two sides and two angles equal.An equilateral triangle has all its sides and angles equal.


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 ratio of the angle maeasures in a triangle is 5 4 1 draw and classify the triangle by its angle measurements?

It will be a right angled triangle with angles of 90, 72 and 18 degrees.


How can a triangle be classified in two ways?

You can classify a triangle by its sides, or by its angles.To classify a triangle by its sides:1- A triangle with three sides that are equal in length is called an equilateral triangle.2- A triangle with two sides of the same length and one different is called an isosceles triangle. 3- A triangle with no sides of equal length is called a scalene triangle. To classify a triangle by its angles: 1- A triangle with three angles that are greater than 0 and less than 90 degrees is called an acute triangle.2- A triangle with one angle that is 90 degrees exactly is called a right angle triangle.3- A triangle with one angle that is greater than 90 degrees is called an obtuse triangle.


If two of a triangle's angles measure 42 degrees and 48 degrees how would you classify that triangle?

It's important to remember that a triangle's angles will always total 180 degrees. 180 - 42 - 48 = 90. The last angle is 90 degrees, so this is a right triangle.


How do you classify a triangle by the sizes of there angles?

All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classed as follows:- Right angle triangle:a 90 degree angle and 2 acute angles Scalene triangle: 3 acute angles Obtuse triangle: an obtuse angle and 2 acute angles Isosceles triangle: 2 equal base angles and an apex angle Equilateral triangle: 3 equal angles each measuring 60 degrees


Calculate the 3rd angle of the triangle Then classify the triangle in two ways?

Not enough information provided. You might be able to use the rule that the sum of all angles is 180 degrees.


If two of a triangle angles measure 42 degrees 48 degrees how would you classify that triangle?

acute , obtuse obtuse or right angle


How do you classify triangles using their attributes?

All triangles have 3 sides and 3 interior angles that add up to 180 degrees and are classified as follows:- Scalene triangle has 3 different acute angles Obtuse triangle has an obtuse angle and 2 different acute angles Right angle triangle has a 90 degree angle Isosceles triangle has 2 equal sides and 2 equal base angles Equilateral triangle has 3 equal sides and 3 equal 60 degree angles


Classify the triangle by its angles and by its sides?

All angles equal = all sides equal = equilateral. Two angles equal = two sides equal = isosceles. All angles different = all sides different = scalene. An isosceles or scalene triangle may be right-angled or obtuse-angled if one of its angles is a right angle or obtuse angle (respectively).
