Triangle description

1. Triangles As we discussed in the introduction, a triangle is a type of polygon, which has three sides, and the two sides are joined end to end is called the vertex of the triangle. An angle is formed between two sides. This is ontrt rt e of the important parts of geometry.  Some major concepts, such as  Pythagoras theorem  and trigonometry, are dependent on triangle properties. A triangle has different types based on its angles and sides.  Shape of Triangle Triangle is a closed two-dimensional shape. It is a three- sidedfdfsggh ghegh ethetyhte rh her polygon. All sides are made of straight lines. The point where two straight lines join is the vertex. Hence, the triangle has three vertices. Each vertex forms an angle.
