3 or 4 triangles, depending on whether it's a triangular or square base.
Three or more, as many as the number of sides of the base. Pyramids can have base that are triangles, squares rectangles, or any planar polygon.
Because if their lateral faces were not triangular they would not be called pyramids!
Yes, three-dimensional figures can have lateral faces that are rectangles, specifically in the case of rectangular prisms and pyramids. A rectangular prism consists entirely of rectangular faces, including its lateral faces. In contrast, a rectangular pyramid has a rectangular base and triangular lateral faces, although it can be visualized with rectangular lateral sections if divided appropriately. Thus, while prisms have all rectangular lateral faces, pyramids typically feature triangular lateral faces.
pyramids have a triangular base. As a triangle has three sides, the pyramid will have three sides. Although you can get square based pyramids which have four sides. ---------------------------------------------- The Egyptian pyramids are 4 sided not 3 sided.
Lateral refers to the sides.
A pyramid is a three-dimensional solid figure characterized by a polygonal base and triangular lateral faces that converge at a single point called the apex. The base can be any polygon, such as a triangle, square, or pentagon, leading to various types of pyramids like triangular pyramids (tetrahedrons) or square pyramids. The lateral faces of a pyramid are always triangles, and the number of these triangular faces corresponds to the number of sides on the base polygon.
"Lateral" means "away from the midline", so the lateral aspects of a pig would be the sides, such as the point of the shoulder, the point of the rump, and the sides of the ribcage.
The lungs lie on the superior lateral sides of the diaphragm.
Cones have curved lateral surface, pyramids don't.
Nine lateral sides,
The lateral sides get taller and narrower. (:
They are the lateral sides or the transverse sides.
