A triangle can be classified according to its sides or the magnitude of its largest angle (two of the angles MUST be acute angles).
All three sides equal: equilateral. Such a triangle must be equiangular, but that term is rarely used.
Two equal angles, third one different (or two sides equal and third different): isosceles.
All three angles different (all three sides different): scalene.
Largest angle = 90 degrees: A right angled triangle.
Largest angle obtuse: An obtuse angled triangle.
What else can I help you with?
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.
What classification of triangle has both line symmetry and rotational symmetry?
Only an equilateral triangle has rotational symmetry.
Can you think of another combination of triangle classification that is impossible?
an Obtuse Equilateral triangle is one.... sadly i don't know any other :(
What is a valid classification of a triangle?
A triangle is a 3 sided polygon whose 3 interior angles add up to 180 degrees
Why is the seven levels of classification triangle upside down?
The seven levels of classification are organized in a triangle because it shows the relationship between each level, with broad categories at the top and specific groups at the bottom. The triangle is upside down to reflect the idea that as you move down the levels, you are moving from general to specific classifications.
What are the two general classification of plane triangle?
1.tri- just like 3 2-Angle- just an angle thats classification for yas all lol
What is the classification by angles and sides of a triangle with three acute angles and three sides of equal length?
equiangular equilateral
What are the classification of triangle according to sides and angles?
Classification of Triangles According to anglesIf one angle of a triangle is a right angle (90°), then it is called a Right triangle. Note that the other two angles are acute.If all the angles of a triangle are acute (less than 90°), then it is called an acute angled triangle.If one angle of a triangle is obtuse (greater than 90°), then it is called an obtuse triangle. Note that the other two angles are acute.According to sides:If any two sides of a triangle are equal, then it is called an Isosceles Triangle. In ABC, AB = AC ABC is isosceles.If all the three sides of a triangle are equal, then it is an Equilateral Triangle. In ABC, AB = BC = CA ABC is equilateral.If no two sides of a triangle are equal, then it is called a Scalene Triangle. In ABC, AB BC CA. ABC is scalene.
What are the Classification of triangle according to sides?
equilateral= all sides are the same length isosceles = two sides are the same, one is different
What is a type of triangle that classifies soils?
A type of triangle used to classify soils is the texture triangle which categorizes soils based on the proportions of sand, silt, and clay they contain. This classification helps determine soil characteristics such as drainage, water holding capacity, and nutrient availability.
What is the classification of a triangle with sides of length 5 inches 12 inches and 13 inches?
A right angle because it complies with Pythagoras' theorem.
Is an isosceles triangle considered a regular triangle?
An isosceles triangle is not a regular triangle because it has 1 side that doesn't equal the other 2. For it to be a regular triangle it will need to have all sides the same length. Here are the three types of triangle classification: In a equilateral triangle or also known as regular triangle "all" sides must have the same length. In an isosceles triangle "at least" two sides must have the same length. In an scalene triangle all sides must be of different lengths Therefor it can be said that a regular triangle is a type of isosceles triangle since it has at least 2 sides of the same length. But remember if one side changes length and 2 remain the same it becomes an isosceles, if all sides are of different lengths then it becomes scalene.
