Math 136 Exam 1 Study Guide
Area scale factor equation - correct answer-A(a) (sf)^2 = A(b)
Base - correct answer-Main polygonal shape
Concave - correct answer-At least one interior angle is greater than 180 degrees and at least
one diagonal is not fully contained in the shape
Congruent shapes - correct answer-They are the same
Convex - correct answer-All interior angles are less than 180 degrees and all diagonals are
within the shape
Edge - correct answer-Line segment where two faces meet
Equiangular - correct answer-Has all equal angles
Equilateral - correct answer-Has all equal sides
Lateral edge - correct answer-An edge that is not a base
Lateral face - correct answer-A face that is not a base
Perimeter scale factor equation - correct answer-P(a) (sf) = P(b)
Polygon - correct answer-A closed plane figure made up of line segments joined end to end
without crossing over (normal shape)
Polyhedral - correct answer-3D shape with many sides and surfaces
Prism - correct answer-A polyhedron with two faces that are parallel and congruent
Prism equation - correct answer-Faces + vertices = edges + 2
Pyramid equation - correct answer-Faces : vertices
Regular - correct answer-A polygon that is both equilateral and equiangular
Similar shapes - correct answer-Must have the same corresponding angles and a scale
factor
Vertex - correct answer-The corner points where two or more edges meet
Volume scale factor equation - correct answer-V2 = V1(sf)^3
