What are pyramids in geometry?
Pyramids are a type of polyhedron that has a polygonal base with triangles extending from it to form an apex. The pyramids of Egypt would be examples of square pyramids because the bottom of them are squares. Likewise, you could have a pentagonal pyramid, hexagonal pyramid, pentagrammic pyramid etc.
How many faces does a square pyramis have?
A square pyramid has 5 faces. The four side faces are triangles, and the base is in the form of a square. This pyramid has 5 vertices and 8 edges.
Can a trapezoid be formed into a square and triangle?
Yes, Some can even be formed into a square and two triangles or a rectangle and one or two triangles. Just drop perpendicular(s) from the vertex (vertices) of the short side to the long side (that is to say, the two sides which are parallel). That will form one or two right triangles and a rectangle of some sort...could be a square--all squares are rectangles but not all rectangles are squares.
How many vertices does an octagonal pyramid have?
An octagonal pyramid has 9 vertices. The base of this shape is an octagon, which will give it 8 vertices when the triangles that form the sides are considered. Those triangles will lead up to the apex (top) of the pyramid, and that will be the 9th vertex.
What quadrilaterals diagonals form 4 congruent triangles?
A square
How many triangles and how many squares form a square pyramid?
A square based pyramid has 4 triangular faces and 1 square face.

What does the term square pyramid mean?
A square pyramid is a pyramid with a square base. It has 4 outer faces, all of which are triangles, that meet at the same point perpendicular to the centre of the base. All pyramids have at least 4 faces (including the base), where the outer faces are all triangular while the base can be trilateral, quadrilateral, or any other polygon. The quadrilateral form (the square pyramid) is the most common form of pyramid, and is the form associated with the Egyptian pyramids.

How do you cut 2 squares and make one?
Cut each square diagonally to give two pairs of right angled triangles. Place all four triangles with their right angles around a point, their hypotenuses will form the sides of the single square.
How many vertices does a primid have?
A pyramid is constructed from a square base (having four corners) and four triangles, rising from each side of the square with their tips meeting at one point. These five two-dimensional shapes form the faces of the three-dimensional shape of the pyramid, that therefore has five vertices (at the four corners of the square and at the point where the triangles meet).
How does a pyramid form?
A pyramid has a pointy top and it is a 3D shape.
Use six toothpicks to construct four congruent triangles?
Arrange the toothpicks to form a square with a diagonal crossing through the center. Then, create triangles by connecting each corner of the square to the center of the diagonal. Each of the four resulting triangles will be congruent to each other.
What do line segment form?
Typically line segments are used to form shapes such as triangles or squares, etc.
Show photo how to divide squares into fourths?
Draw diagonal lines to form a diagonal cross in each square, so dividing all the squares into four triangles in each. A pencil and a straightedge is all that is needed, no measuring to form vertical and horizontal lines to divide each square into four smaller squares is required. Can't show a photo or graphics in Answers, I believe.
Is a octahedron a pyramid?
It can be but need not be. A heptagon-based pyramid is an octahedron. However, the term is often used for the Platonic solid bounded by eight equilateral triangles - in the form of two square based pyramids stuck together base-to-base.
