Classifications by side length or comparison of angles and sides:
scalene - no sides or angles equal
isosceles - two sides and angles equal (congruent)
equilateral - all sides and angles equal (all 60° angles)
Classifications by included angles :
right triangle - contains a 90° angle (right angle)
oblique triangle - has no right angle
acute triangle - contains all angles less than 90°
obtuse triangle - contains one angle greater than 90°

Why do triangles have different names?
Triangles have different names based on their side lengths and angle measures. For example, a triangle can be classified as equilateral, isosceles, or scalene based on its sides, while it can be acute, right, or obtuse based on its angles. These classifications help in understanding their properties and relationships in geometry. Additionally, naming triangles aids in clear communication and analysis in mathematical contexts.
What is the other triangles names beside equaladeral?
Besides equilateral triangles, other types include isosceles triangles, which have two sides of equal length, and scalene triangles, where all sides are of different lengths. Additionally, right triangles have one angle that measures 90 degrees. Each type has distinct properties that define its shape and angles.
