All triangles have 3 sides and 3 interior angles that add up to 180 degrees and they are classified as follows:-
Scalene has 3 acute angles of different sizes and different sides
Right has a 90 degree angle and 2 acute angles with 2 sides being perpendicular
Obtuse has an obtuse angle and 2 different acute angles and different sides
Isosceles has has 2 equal angles and an apex angle and 2 equal sides
Equilateral has 3 equal angles each being 60 degrees and 3 equal sides
Acute angle is greater than 0 but less than 90 degrees
Right angle is 90 degrees
Obtuse angle is greater than 90 but less than 180 degrees

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
Triangle with no equal sides angles or sides?
A triangle with no equal sides or angles will always be classified as 'scalene'.
How can you classify triangles using angles and using sides?
Using angles and sides:All three angles equal. This implies that all three sides are of the same length. The triangle may be known as an equiangular triangle but, more commonly, equilateral triangle.Two equal angles, which implies that two sides are equal. The triangle is an isosceles triangle.All three angles (and therefore sides) are different. This is known as a scalene triangle.Using angles only:If all angles are less than 90 degrees it is an acute angles triangle.If one angle is 90 degrees, a right angled triangle.If one angle is greater than 90 degrees then an obtuse angled triangle.
Why does a triangles have three sides and three angles?
That is the definition of a triangle. If it did not have three sides it would not be a triangle. If it did not have three angles, it would not be a 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 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.
Classification of triangle?
Classification of triangles according to sides: -Scalene Triangle - a triangle with no 2 congruent sides. -Isosceles Triangle - a triangle with at least 2 congruent sides. -Equilateral Triangle - a triangle with 3 congruent sides. Classification of triangles according to angles: -acute triangle - a triangle with 3 acute angles. -right triangle - a triangle with one right angle. -equiangular triangle - a triangle with 3 congruent angles. -obtuse triangle - a triangle with one obtuse angle.
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).
How do you classify triangles by angles and sides?
you classify triangles by seeing the sides as if the triangle was isosceles, equilateral, or scalene Isosceles= two angles equal or two sides equal Equilateral= all angles equal and all sides equal Scalene= all angles different and all sides different. ☻☻ I HOPE IT HELPED☻☻
Triangle with no equal sides angles or sides?
A triangle with no equal sides or angles will always be classified as 'scalene'.
How do you classify a triangle with no congruent sides?
scalene triangle
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
How do you classify a quadrilaterals?
You classify a quadrilateral by its sides, angles, and its vertices.
How many sides and angles does a scalene triangle have?
Sides and Angles in a TriangleBy definition, a triangle has three sides. Since the number of sides and angles is equal, it would also have three angles.
