A pyramid could be constructed from 4 or more triangles.
It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
An hexagon or a 6 sided shape
A dodecagon is a 12 sided shape made from 10 triangles
A pyramid could be constructed from 4 or more triangles.
A tetrahedron; a shape made of four triangles.
It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.
The three-dimensional shape consisting of 4 triangles is called a pyramid, or a triangular prism.
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.
Yes, if you put them together correctly.
An hexagon or a 6 sided shape
A dodecagon is a 12 sided shape made from 10 triangles
A tetrahedron has four equilateral triangles as sides
It doesn't exist. The least number of sides for a 3-D shape only made of triangles is 4.
A Triangular Pyramid has 4 triangles and 1 square.
