Question

How many elements does a triangle has?

Answer 1

Elements of a triangle

A triangle has $3$ sides , $3$ angles and $3$ vertices.
Side – A line that connects two vertices to create the contour of a $2\mathrm{D}$ and $3\mathrm{D}$ shape is referred to as a shape’s side.
Angle – In Plane Geometry, an angle is indeed a figure created by $2$ rays or lines that share the common endpoint.
Vertices – The spots where $2$ or even more line segments and sides intersect in a shape are called vertices (like a corner).

Elements of triangle are : Sides $\left(a,b,c\right)$, angles $(x,y,z)$ and vertices $(A,B,C)$

Hence, triangle has $9$ elements
