The tetrahedron has 4 equilateral triangles as its faces.
a larger equilateral triangle
It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.
a square based pyramid.
A four faced figure is a tetrahedron. If they are all congruent triangles, they are all equilateral triangles and it is a regular tetrahedron - one of the 5 Platonic Solids.

Differences: Squares have 4 sides / equilateral triangles have 3 sides. Squares have 90 degree angles / equilateral triangles have 60 degree angles. Squares have 2 diagonals / equilateral triangles have none Similarities: All sides of the shape are congruent All angles of the shape are congruent
The tetrahedron. If one of the four triangles is equilateral and all others are isosceles, then one might also call it a (triangular-based) pyramid.
A TETRAHEDRON. Incorrectly named as a 'triangular pyramid'.
a square based pyramid.
A square * * * * * No, the shape is equilateral. You can have equilateral triangles, 4-sided shapes such as rhombi, or polygons with 5 or more sides. A square is just one specific example.

In an octagon, there are 20 equilateral triangles. Each side of the octagon can form two equilateral triangles with the adjacent sides, resulting in 8 equilateral triangles. Additionally, the diagonals of the octagon can form 12 more equilateral triangles. Therefore, the total number of equilateral triangles in an octagon is 8 + 12 = 20.
Put four equilateral triangles so that each one of them has a vertex at a single point and the triangles abut one another. The shape will be 4/6 (= 2/3) of a regular hexagon.
No, a square is not made up of four equilateral triangles. A square has four equal sides and four right angles, while equilateral triangles have three equal sides and three equal angles, each measuring 60 degrees. However, you can arrange two equilateral triangles to form a rhombus, which can be manipulated to fit within a square, but they do not constitute the same geometric shape.
