sum of the areas of the faces of a closed 3d object - correct answer ✔✔surface area
measure of the capacity of a 3d object - correct answer ✔✔volume
3d geometric object consisting of 2 parallel and congruent circles and the parallel line segments
that join corresponding points on the circles - correct answer ✔✔cylinder
3d geometric object consisting of all line segments joining a single point to every point of a
circle - correct answer ✔✔cone
the set of points in space that are equidistant from a given point called the center - correct
answer ✔✔sphere
(by vector PQ) a transformation in which if A is any point in the plane and the image of A is A',
then AA' and PQ are equal vectors; that is, line AA' and line PQ are parallel and equal in length -
correct answer ✔✔translation
set of points that result from the motion of an object by a translation, a rotation, or a reflection
- correct answer ✔✔images
an arrow that gives the direction and distance that a point is moved during a translation -
correct answer ✔✔translation vector
a movement of the points of a plane that may change the position or the size and shape of
objects - correct answer ✔✔transformation
, a transformation of the plane that changes the shape of an object - correct answer ✔✔shearing
transformation that only changes the size of an object - correct answer ✔✔scaling
transformations of the plane that preserve distances between points - correct answer ✔✔rigid
motions
coincide when superimposed - correct answer ✔✔congruent
(about a point P through an angle pheta) a transformation of the plane in which the image of P
is P and, if the image of A is A', then like PA is congruent to like PA' and angle APA' = pheta. Point
P is called the center of the rotation - correct answer ✔✔rotation
(in a line l) is a transformation of the plane in which the image of a point P on l is P, and if A is a
point not on l and if the image of A is A', then l is the perpendicular bisector of line AA' - correct
answer ✔✔reflection
a pair of points, one of which is the original point and the other of which is the image of that
point under a transformation - correct answer ✔✔corresponding points
a point whose location remains the same under a transformation - correct answer ✔✔fixed
points
(of a circle) the point that is equidistant from all points on the circle - correct answer ✔✔center
lwh - correct answer ✔✔volume of rectangular prism
pi X r^2 X h - correct answer ✔✔volume of cylinder
