Triangles (four of) and a square.
Five. Four triangles and one square make up a square pyramid.
There are technically many shapes that could be put into the form of a triangle, but only triangles can make real triangles (without getting into more complicated shapes).
If it has a square base, one. Squares don't crop up all that often.
Two squares Two triangles
This sounds like you are talking about a pyramid. Pyramids in Geometry are not restricted to the square pyramids you may be used to seeing in pictures of from Egypt. Pyramids are named after the type of polygon that make up their base. In Egypt, since the bases of those pyramids are squares, they are known as square pyramids. If you had a pyramid with a pentagon for a base, then it would be a pentagonal pyramid. Pyramids always have triangles for sides that meet at a common point at the top which is known as the apex.

A square can be drawn with four lines.
There are 4 triangles that make up a pyramid. 4 on the sides and on the bottom a square or rectangle.
A rectangle and 4 triangles.
One square and four triangles.
Plane shapes you draw on paper. Solid shapes can be picked up. Examples of plane shapes would be circle, square, triangle, etc. Examples of solid shapes would be a sphere, a cube, pyramid, and so on. ■
Yes. They have perpendicular bisectors in the four triangles that make up four of the five sides of a square-based pyramid
square shaped head
A polygon with n sides, and n triangles, where n ≥ 3. Most commonly, the polygon at the base is a triangle or a square. If the base polygon is regular and the pyramid is a right pyramid (ie apex above the centre of the basal polygon), the triangles will be isosceles.
square based pyramid is made up of four triangle and a flat square base and it is a solid figure
