Pyramid

Image
  Learning Outcomes   1.Students will be able to identify pyramids from other 3D shapes and describe their key features (such as base shape, apex, faces, edges, and vertices). 2. Students will be able to classify pyramids based on the shape of their base (e.g., triangular pyramid, square pyramid, etc.). 3.Students will be able to apply formulas to calculate the surface area . 4.Students will be able to compare pyramids with other three-dimensional figures . Notes Definition of pyramid   A pyramid is a 3D shape with a polygonal base and triangular faces all around that meet at a common point called apex. Real Examples Important parameters   Base edge: The sides of the polygon forming the base of the pyramid. Lateral edge: Edge formed between the apex and a vertex of the polygonal base. Height: Perpendicular distance from apex to the base. Slant height: Distance from the apex to the midpoint of a side of the base. Surface area:Base area+ area of triangular faces. ...
