There are three main types of triangle:
- Scalene - all angles are different and all sides are different lengths
- Isosceles - Two sides are equal in length and the two angles (between the third side and the two sides of equal length) are equal
- Equilateral - All three angles are equal (at 60°) and all three sides are of equal length.
If all angles are less than 90° then the triangle can also be described as an Acute triangle; an equilateral triangle is acute by definition as all angles are 60° which is less than 90°.
A Scalene or Isosceles triangle can also be described as a Right angle triangle if one angle is 90° (a right angle); in the isosceles triangle this is the angle between the sides of equal length.
A Scalene or Isosceles triangle can also be described as an Obtuse triangle if one angle is greater than 90°; in the isosceles triangle this is the angle between the sides of equal length.

Find the area of a right triangle?
Simple. Just multiply the base by the height of the triangle, and divide it into two. This works for all types of triangles.
How do you find the area of an irregular triangle?
Simple. Just multiply the base by the height of the triangle, and divide it into two. This works for all types of triangles.
What is a three sided shape called?
A triangle - It comes in three types -the Equilateral triangle - all sides of equal lengththe Isosceles triangle - two sides of equal lengththe Scalene triangle - all sides of different length
Which triangle has no two sides congruent?
A triangle which has no two sides congruent is called a Scalene Triangle.
What is a triangle with an obtuse angle called?
There are five different types of triangles named after their angles. Right triangle, Acute triangle, Isosceles Triangle ,equilateral triangle, and obtuse triangle. The Obtuse Triangle is the triangle with an obtuse angle.

What are three different ways a triangle can be classified?
There are two types of triangle: 1. Scalene triangle - no sides have the same length 2. Isosceles triangle - at least two sides have the same length a. Equilateral triangle - an isosceles triangle with 3 sides the same length.
Are types of scalene triangles are parallelogram?
No triangle is a parallelogram. No two sides are parallel.

Is a scalene triangle always a isosceles?
No, those are two different types of triangles. An isosceles triangle has two sides of the same length and one side of different length; a scalene triangle has three sides which are all of different length.
What is a triangle and what are its types in geometry?
a triangle is a three sided shape. there are 4 types of triangles: scalene, isosceles, right angled triangle and an equilateral triangle.
