Oh, dude, a square base pyramid is like the cool kid of shapes. It's got that square base, you know, four sides all equal and stuff, and then it's got this pointy top that's like, "Look at me, I'm a pyramid!" So, yeah, it's basically a square with a triangle on top, but way more awesome.
A square and and a triangle
The base of square pyramid is a square, as you may have guessed. If you measure one side of the square base, you'll have discovered the length of a side of the base. A side squared (a side times a side) will give you the area of the base of a square pyramid. If you have the area of the base, you can find the length of a side of the base by finding the square root of the area of the base. In the case of a square pyramid, if you are given the length of a side and either a vertex angle or the angle between the base and a side, you'll have an isosceles triangle to deal with. (There are four isosceles triangles that make up the faces of the square pyramid, as you probably figured out.) This involves a bit of trigonometry, and there are some other questions here that will help you figure that out.
There are five faces in a triangular pyramid. Gosh person, use your math book! Sorry you are wrong. It depends on the base if it is a square it has 5 surfaces if the base is a triangle it has 4 surfaces. So you must examine your pyramid carefully so as not to make a simple mistake.
the base is a 2-d square with joined triangles, meeting together to make a corner at the top, the triangles height can be any height, or the square can be any size
The only thing I can come up with would be a tetrahedron. You could make a pyramid with a square (open) base, I guess.
A pyramid has a triangle for each side of the base, thus for a square pyramid you'll need one square (for the base) and 4 triangles.
Triangles (four of) and a square.One square as base and four triangles as sides.
A square and and a triangle
To make a rectangualr pyramid,you need a rectangle for the base, and four triangles on the sides.
A triangle and a square
Your base is a square and the other faces are triangles.
the base is both squares
make a square base with the four sider make 4 triangles that are on eachside
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.
