graph in which information is represented using bars of various lengths
to show values of a particular category.
, or x^n, the "x" is the base. The base number gets multiplied
by itself the number of times indicated by the exponent, "n".
2^3 = 2x2x2.
of a triangle
The side of a triangle to which an altitude is drawn.
of a trapezoid The
parallel sides of a trapezoid.
of an isosceles triangle
Two angles of an isosceles triangle whose vertices are the endpoints of
the base of the triangle.
||The base angles
on an isosceles triangle are congruent.
of a trapezoid
Two angles whose vertices are the endpoints of a base of the trapezoid.
The base angles on an
isosceles trapezoid are congruent.
In this example, angles
A and B are congruent base angles as are angles D and C.
an isosceles triangle
The side opposite the vertex angle.
A number is between two others if it is greater than one of them and less
than the other.
A point is between two other points on the same line if its coordinate
is between their coordinates.
A statement that includes a conditional and its converse. It may be written
in the form p=>q and q=>p, or p<=>q, or "p if and only
It is raining if and only if drops of water are
falling from the sky.
This statement is a biconditional because it is
true when read front to back and also when it is read back to front,
Drops of water are falling from the sky if and
only if it is raining.
A good definition
consists of a true conditional and its converse, which also must be true.
So biconditional statements are important to find.
A space figure has bilateral symmetry if and only if there is a plane
over which the reflection image of the figure is the figure itself.
A word name for 1,000,000,000 or .
A word for 0.000000001 or x^-9.
An algebraic expression with exactly two terms.
x^2 - 4
3x^2y + 7x
A point, line, ray, or plane which divides a segment,
angle,or figure into two parts of equal measure.
of an angle
The ray in the interior of an angle that divides the angle into two angles
of equal measures.
of a segment
A line, ray, or segment which intersects a segment at its midpoint but
does not contain the segment.
A a right prism whose faces are rectangles.
[ ] Grouping symbols which serve the same role as parentheses.
