12) practice: organizing information
fill in the blanks to define a pyramid and its parts.
a pyramid is a ______ made of one polygon base, a point not on the same plane, and all the ______ between them.
- bases: one ______ face (like a bottom)
- lateral faces: all ______ that meet at the same point (like sides)
- altitude: the line segment whose length is the ______ of a pyramid
13) practice: organizing information
complete the chart to compare pyramids.
| | regular pyramid | irregular pyramid |
|--|--|--|
| base | ______ polygon | irregular polygon |
| lateral faces | ______ triangles | not congruent triangles |
| vertex | ______ over base | not centered over base |
| altitude | through ______ | not through center |
14) practice: making mental images and drawing inferences
fill in the blanks.
compare a line segment to a pyramid
- line segment: two points and all the ______ between them
- pyramid: a polygon and a point not on the same plane and all the ______ between them
15) practice: using visual cues
a pyramid is named for its base. identify the polygon base. then name the pyramid.

Question

Accepted Answer

# Brief Explanations:
A pyramid is a three - dimensional shape. Its base is a polygon, lateral faces are triangles, altitude is related to its height. For regular pyramids, base is regular polygon, lateral faces are congruent triangles, vertex is centered over base and altitude goes through center. A line segment has points and all points between them, and a pyramid has a polygon, a non - coplanar point and all points between them.
# Answer:
12) A pyramid is a **polyhedron** made of one polygon base, a point not on the same plane, and all the **line segments** between them.
 - bases: one **polygon** face (like a bottom)
 - lateral faces: all **triangles** that meet at the same point (like sides)
 - altitude: the line segment whose length is the **height** of a pyramid
13)
 - base: **regular** polygon
 - lateral faces: **congruent** triangles
 - vertex: **centered** over base
 - altitude: through **center**
14)
 - Line segment: two points and all the **points** between them
 - Pyramid: a polygon and a point not on the same plane and all the **line segments** between them
