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 paralellagram ----------------------- Usually called "irregular" since "regular" polygons have equal sides, by definition. The word "scalene" typically refers to triangles with three unequal sides.
Another word is shape. A polygon is a shape with different kinds of sides.
A square.
It means a shape of many 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.
Because an heptagon is a 7 sided shape and the word polygon means many sides.
Depends, what shape are you talking about? Is it a triangle with no equal 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.
You specify shapes by the number of sides (or edges, different name) they have. The suffix -gon at the end of a word show how many sides it has in the words. For example, an octagon has eight sides; so if you see a shape with eight sides, it's an octogon. All shapes are known as polygons, which means it has three or more sides.
It means that the sides are of equal lengths and that the interior angles are of equal sizes
