Unit 9: Geometry – 6th Grade Lesson 6: solid figures

Cornell Notes Header Topic: Geometry 6th Grade (Unit 9 pg. 6) E. Q.: How are two-dimensional and three-dimensional figures related? Name: _____________________________ Date: _____________________________ Class: _____________________________ Chp. 10 Lesson 5 –Solid Figures

Parts of three dimensional figures face – the polygons that form the solid figure. edge – the segments where the faces of a figure meet. vertex – the point where edges meet. (The plural is vertices.) edges face vertex

Counting faces, edges & vertices ex. Ex. Count the number of faces, edges, and vertices of the square pyramid shown. faces: 5 edges: 8 vertices:

Classifying solids prism – a solid with two parallel bases that are congruent polygons. Ex. rectangular prism and triangular prism cylinder – a solid with two parallel bases that are congruent circles. Ex. pyramid – a solid made with polygons. The base can be any polygon, and the other polygons are triangles that share a common vertex.

Classifying solids Continued cone – a solid with one circular base and a vertex that is not in the same plane. Ex. sphere – the set of all points that are the same distance from a pointed called the center.

How to draw a solid Draw a triangular prism. (textbook pg. 542) (1) Draw the congruent bases (2) Connect the corresponding vertices. (3) Make hidden lines by partially erasing lines.
