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°
*Note that a triangle can be more than one type. A right triangle is a special case of either a scalene or isosceles triangle.

What is the ratio of 4 triangles to 3 circles?
The ratio of 4 triangles to 3 circles is expressed as 4:3. This means for every 4 triangles, there are 3 circles. Ratios can also be simplified or represented in different forms, but in this case, 4:3 is already in its simplest form.
How many triangles are in a 4-sided polygon?
You could draw four different triangles in a 4-sided polygon, but two are enough to define the polygon.
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 are the 4 different triangles called?
isosceles, scalene , equilateral, right angle triangle
What is the different between all of the 4 triangles?
Equilateral triangles have 3 sides all of the same lengths and the three angles are equal (60°). Isoceles triangles have two sides of equal length with both of those side angles being equal while the other is different. Scalane triangles have all sides of different lengths and different angles. Right angled triangles have one angle of 90° and the other two will total 90°.
