Transformati on A line that crosses two or more other
lines What is a transversal?
Two angles formed by two lines and a transversal that are on opposite sides of the transversal and between
the two given lines What are alternate interior angles?
A line, ray, or segment that intersects a segment at its midpoint and is perpendicular to it
What is the perpendicular bisector?
To divide an angle or segment into two congruent angles or segments
What is bisect? A closed figure in a plane made of line segments that
intersect only at their endpoints What is a polygon?
An angle whose vertex is at the center of the circle What is a central
angle? The distance around the circle
What is the circumference? Any line segment whose end points
lie on the circle What is a chord? The distance along
the circle intercepted by two chords or radii What is the arc
length? The point where the tangent line intersects the circle
What is the point of tangency? The amount of
space taken up by a solid or capacity What is a volume?
On a polyhedron, the intersection of three or more faces
What is a vertex? The sum of the areas of the faces in a polyhedron
What is the surface area? A perpendicular
segment that joins the planes of the bases of a prism. What is the
altitude? If, in two solids of equal altitude, the sections made by planes parallel to and at the same
distance from their respective bases are always equal, then the volumes of the two solids are equal What is
Cavalieris Principle? An example that shows a statement
false What is a counterexample?
A rule used to determine whether triangles are congruent by comparing the three
sides What is SSS or Side-Side-Side theorem?
Double Points! A rule used to
determine whether triangles are congruent by comparing two angles and the side between them
What is ASA or Angle-Side-Angle Conjecture (Theorem)?
When all angles of one figure are congruent to the corresponding angles in another
figure What are similar figures?
A transformation that preserves size and shape. The image will be congruent to the original figure
What is isometry ? A polygon with four
sides What is a quadrilateral?
An equiangular quadrilateral What is a rectangle?
An equilateral quadrilateral What is a
rhombus? Having all the properties of a rectangle and a
rhombus What is a square? A quadrilateral with
opposite sides parallel and congruent. What is a parallelogram?
The image of a figure that has been slid to a new position without flipping or turning
What is a translation? A transformation
that does not alter the size or shape of the figure What is a rigid
transformation or motion? The direction of rotation when the
top of a figure turns to the left What is counterclockwise
? In a rotation, the point that does not move
What is the center of rotation? Double
Points! The line of reflection is this from the figure and
its image What is equidistant?
Final Question It is the set of points that are a given
distance from a given point What is a sphere? To be a circle the definition had to include on a plane. The set
of points thereby define a space and a 3-D figure.
