MATH 201 TEST 3 QUESTIONS WITH VERIFIED
ACCURATE ANSWERS
sum of the areas of the faces of a closed 3d object - Answers -surface area
measure of the capacity of a 3d object - Answers -volume
3d geometric object consisting of 2 parallel and congruent circles and the parallel line
segments that join corresponding points on the circles - Answers -cylinder
3d geometric object consisting of all line segments joining a single point to every point
of a circle - Answers -cone
the set of points in space that are equidistant from a given point called the center -
Answers -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 - Answers -translation
set of points that result from the motion of an object by a translation, a rotation, or a
reflection - Answers -images
an arrow that gives the direction and distance that a point is moved during a translation
- Answers -translation vector
a movement of the points of a plane that may change the position or the size and shape
of objects - Answers -transformation
a transformation of the plane that changes the shape of an object - Answers -shearing
transformation that only changes the size of an object - Answers -scaling
transformations of the plane that preserve distances between points - Answers -rigid
motions
coincide when superimposed - Answers -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 - Answers -rotation
