QUESTIONS GRADED A+
◉ 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.
◉ 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.
◉ 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.
◉ 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.
◉ rectangle. Answer: Quadrilateral with four right angles, equal
opposite sides, and two sets of parallel opposite sides.
