Triangles.
All triangles have three sides
All triangles have three vertices.
A three-sided shape is called a triangle. There are three types of triangles: equilateral triangles, iscosceles triangles, and scalene triangles. Equilateral triangles have all equal sides and angles; iscosceles triangles have two congruent legs and a base, and scalene triangles do not have any equal sides or angles.
Because all other polygons are made from triangles as for example an 8 sided octagon has 6 triangles within it or a 6 sided hexagon has 4 triangles within it.
Triangles.
TRUE for 2-dimensional figure. False for 3-dimensional figures.
Because there are 540 interior degrees in a five sided figure and the total sum of three triangles is 540 degrees
All triangles have three sides
All triangles have three vertices.
There are all three sided polygons. The sides can be equal in length or unequal.
