Unit 8 Flashcards
Cavalieri’s principle states that if two geometric solids with the same height have the same cross-sectional area at every level, then they have the same _____.
volume
A(n) _____ point is a point that lies on one of the three planes of a three-dimensional coordinate system and corresponds to two of the numbers in an ordered triple.
projected
The _____ height of a cone is the distance from the apex of a right cone to a point on the edge of the base.
slant
The ____ of a pyramid is a segment that extends from the apex of a pyramid to the plane of its base and is perpendicular to the plane of the base.
altitude
The _____ height of a pyramid is the distance from the apex to the midpoint of an edge where a lateral face meets the base.
slant
A(n) _____ projection is a form of three-dimensional projection that presents six views of an object in which a sight for each view is perpendicular to the plane of the figure.
orthographic
The lateral faces of a regular pyramid are all congruent _____ triangles.
isosceles
A(n) _____ is a two-dimensional diagram of the surfaces of a three-dimensional figure that can be folded to form a geometrical solid.
net
A(n) _____ is a circle formed by the intersection of the surface of a sphere with a plane that passes through the center of the sphere.
great circle
The _____ opposite the base where all the lateral faces meet is called the apex of a pyramid.
vertex
The curved surface that connects the two bases of a cylinder is called the _____ surface of a cylinder.
lateral
The lateral surface of a cone is the curved surface that connects the _____ of a cone to the apex of the cone.
base
The _____ of a cylinder is a segment that extends from one base of a cylinder to the other base and whose endpoints are the centers of the two bases.
axis
The altitude of a cone is a segment that extends from the apex of a cone to the plane of its _____ and is perpendicular to the plane of the base.
