Chapter 10- Volume Flashcards
polyhedron
a solid formed by polygons that enclose a single region of space
face
the flat surfaces of a polyhedron
edge
a segment where two faces intersect
vertex
the point of intersection of three or more edges
regular polyhedron
a polyhedron with each face a regular polygon and each face is congruent to the other faces
icosahedron
20 faces
prism
a special type of polyhedron with two faces called bases that are congruent, parallel polygons
pyramid
a special type of polyhedron with only one base
cylinder
a solid with a curved surface consisting of two congruent, parallel circles and their interiors, and the segments having an endpoint on each circle that are parallel to the segment between the centers of the circles
cone
a solid with a curved surface consisting of a circle and its interior, a point not in the plane of the circle and all points on the line segments connecting that point to a point on the circle
lateral face
parallelograms that connect the corresponding sides of the bases
lateral edge
where the lateral faces meet
altitude
any perpedicular segment from one base to the plane of the other
perpendicular segment from vertex to base
axis
the segment connecting the centers of the bases
sphere
a solid with a curved surface representing the set of all points in a space at a given distance from a given point
