A triangle.
A shape that has three sides is spelled "triangle." The word comes from the Latin "triangulus," meaning "three corners." Triangles can vary in type, such as equilateral, isosceles, and scalene, based on the lengths of their sides.
Mo such shape/thing as a 'polgon'. If you mean ' polygon'. The word 'polygon' means a 2-dimensional shape (--gon) of many sides (poly--). So the word 'polygon' mean an many sided shape. For a specific number of sides it becomes;- trigon ( triangle) 3 sides quadragon ( quadrilateral ) 4 sides pentagon 5 sides et seq.,
Depends, what shape are you talking about? Is it a triangle with no equal sides?
A triangle has three sides. The word 'tri' means three so anything with 'tri' in means it has three 'somethings.' For example, a tricycle has three wheels, and a triathlon is made up of three sports (swimming, running and cycling).
A pyramid with a triangle as base is considered as a tetrahedron. It is a three dimensional polyhedron with 4 equilateral triangles as its sides. If one would look at the word tetrahedron, it literally means "with four planes".
A square.
It means a shape of many sides.
A shape that has three sides is spelled "triangle." The word comes from the Latin "triangulus," meaning "three corners." Triangles can vary in type, such as equilateral, isosceles, and scalene, based on the lengths of their sides.
Pentadecagon is the word that means 15-sided polygon.
congruent means that all sides of the shape or object are equal to each other and are the same.
A shape with 5 sides is called a pentagon.
Regular.
The word 'tri' means three so anything with 'tri' in means it has three 'somethings' e.g. Tricycle - Three wheels Triathlon - Made up of three sports (swimming, running and cycling) Thus a triangle has three sides.
By definition, an equilateral triangle has congruent sides. "Equi"has the same root as the word "equal," which is synonymous with "congruent," and "lateral" is based on the Latin word for "side." Thus, the word "equilateral" actually means "equal sides," which means they are "congruent."In fact, an equilateral triangle has three equal sides and three equal angles.
Because an heptagon is a 7 sided shape and the word polygon means many sides.
Mo such shape/thing as a 'polgon'. If you mean ' polygon'. The word 'polygon' means a 2-dimensional shape (--gon) of many sides (poly--). So the word 'polygon' mean an many sided shape. For a specific number of sides it becomes;- trigon ( triangle) 3 sides quadragon ( quadrilateral ) 4 sides pentagon 5 sides et seq.,
