**TRIANGLE**(PointA, PointB, PointC)

where,

**PointA, PointB, PointC **- represents the 3 points.

Related functions:-

**TRIANGLE.PERIMETER()** - returns the sum of sides.

**TRIANGLE.AREA() -** returns the region bounded by triangle.

**TRIANGLE.CIRCUMCIRCLE() -** A circle which passes through all three vertices of triangle called circumcircle. It also called as circumscribed circle.

**TRIANGLE.INSCRIBEDCIRCLE()-** A circle inside a triangle whose edges are tangent to the circle is called inscribed circle**.**

**TRIANGLE.SIDETYPE() -** returns the type of triangle by their side such as Scalene, Isosceles or Equilateral triangle.

**TRIANGLE.ANGLES() -** returns the angles of triangle**.**

**TRIANGLE.ANGLETYPE() -**returns the type of triangle by their angle such as Acute, Right, Obtuse or Equiangular triangle.

'

A polygon with three corners or vertices and three sides or edges which are line segments.Triangles can be classified according to the relative lengths of their sides such as Equilateral,Isosceles and Scalene triangle.

TRIANGLE

Lets see an example in (Column1, Row2)

=TRIANGLE(R1C1, R1C2, R1C3)

The function returns the shape.

Consider an another example(Column1, Row3)

=TRIANGLE.PERIMETER()

TRIANGLE returns the perimeter(12).

An example in (Column1, Row4)

=TRIANGLE.CIRCUMCIRCLE()

It returns the shape (CIRCLE).

An example in(Column1,Row5)

=TRIANGLE.INSCRIBEDCIRCLE()

It returns the shape (CIRCLE).

An example in (Column1, Row6)

=TRIANGLE.SIDETYPE()

It returns the type of triangle.

An example in (Column2, Row2)

=TRIANGLE.ANGLES()

It returns the angles.

An example in (Column2,Row3)

=TRIANGLE.ANGLETYPE()

It returns the type of angle.
