**triangle**is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices*A*,*B*, and*C*is denoted*ABC*.
In Euclidean geometry any three non-collinear points determine a unique triangle and a unique plane (i.e. a two-dimensional Euclidean space). (Source : Wikipedia)

Understanding Types of Manipulation is always challenging for me but thanks to all math help websites to help me out.

## List of learndifferent types of triangles

**Different types of triangles classified by sides:**- Equilateral triangle
- Isosceles triangle
- Scalene triangle.

**Different types of triangles classified by angles:**- Acute
- Right
- Obtuse

## Brief description for learn different types of triangle:

**Learn Equilateral triangles:**
Equilateral triangle is the one of the different types of triangles. In
equilateral triangles all sides are equal length. The equilateral
triangles are regular polygons. The equilateral triangles each angle is
measuring 60°.

**Learn Isosceles triangles:**

Isosceles triangle is the one of the different types of triangles.
These isosceles triangles two angle are equal measure. The Isosceles
triangles in any of the two sides are equal length. These isosceles
triangles the base angles are the angles opposite the two equal sides.

**Learn scalene triangles:**

Scalene triangles are the one of the different types of triangles. The
Scalene triangles don’t usual triangles. Some triangles are drawn at
random would be scalene. The scalene triangles interior angles are
always different measure. Scalene triangles all three angles are
different measure and all the sides are different lengths.

**Learn acute triangles:**

Acute triangles are one of the different types of triangle. It’s
classified by its angles. Acute triangles each angles are less than 90
degree.

**Learn Right triangles:**
Right triangles are the one of the different types of triangles. The
right triangles are also called as right angle triangles or rectangle
triangles. This right triangles one angle must be 90 degree. The right
angle triangles opposite sides are the hypotenuse; hypotenuse is the
longest side of the right triangle. Remaining two sides are called as
legs. In right triangles the lengths of the sides are connected by the
Pythagorean Theorem.

**Learn obtuse triangles:**

Obtuse triangle is one of the different types of triangles. It’s
classified by its angles. Triangles any one angle is measures more than
90° is an obtuse triangle or obtuse-angled triangles.
