line .......Answer.........A straight one-dimensional figure that
extends infinitely in both directions.
perpendicular .......Answer.........Describes lines intersecting each
other to form a 90 degree, or right, angle.
circle .......Answer.........The set of all points that are equidistant
from a point.
radius .......Answer.........The distance from the center of a circle or
sphere to any point on the outer edge.
,age 2 of 34
isosceles trapezoid .......Answer.........Quadrilateral with one pair
of parallel opposite sides (the bases) and another pair of equal
opposite sides.
interior angle .......Answer.........An angle inside a shape between
two joined sides.
square .......Answer.........A quadrilateral with four equal sides
and four 90° angles.
regular polygon .......Answer.........A polygon with equal sides and
equal angles.
central angle .......Answer.........Shape formed when 2 lines or
rays meet with vertex meets only the center point of the circle.
hypotenuse .......Answer.........The largest side of a right triangle,
opposite the right angle. Only right triangles have a hypotenuse.
,age 3 of 34
kite .......Answer.........Quadrilateral with two sets of adjacent
equal sides and one set of equal opposite angles.
reflex angle .......Answer.........Angles greater than 180°.
vertical line .......Answer.........A line that runs up and down on the
coordinate plane, parallel to the y-axis. It has no run, or change
in x-value.
parallel .......Answer.........Two lines, line segments, rays, or planes
that are the same distance from one another and never intersect.
trapezoid .......Answer.........Quadrilateral with one pair of
parallel opposite sides.
bisect .......Answer.........To divide into two equal parts.
isosceles triangle .......Answer.........A triangle with two equal sides
and two equal corresponding angles.
, age 4 of 34
angle .......Answer.........The amount of rotation (often measured in
degrees) needed to make one line segment, ray, or line identical
with another line segment, ray, or line.
inscribed angles .......Answer.........Shape formed when 2 lines or
rays meet with a vertex that meets the circumference of a circle.
vertex .......Answer.........A point where two line segments meet to
form an angle.
irregular polygon .......Answer.........A polygon whose sides are
not all equal and whose angles have different measures.
straight angle .......Answer.........An angle that measures 180
degrees.
line segment .......Answer.........Shortest distance between two
points; completely straight with two endpoints.
