That depends on what the side lengths are. Until the side lengths are known, the triangle can only be classified as a triangle.
I would place this triangle in the category of isosceles triangles, because the 10m side and the 10m side have equal lengths.
scalene triangle
A triangle is classified as a 3 sided polygon.
math
If the triangle is less than 90 degrees, it is an acute triangle
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!
In a right triangle, a2 + b2 = c2, where c is the longest side. If the square of the longest side is more than the sum of the other two squares, the triangle has an obtuse angle. If it is less, all angles are acute.
One rectangle and two triangle
It is an obtuse triangle
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.
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.
