WGU D127 - Mathematics for Elementary Educators III EXAM
COMPREHENSIVE QUESTIONS AND ANSWERS 2024
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.
sector - (answer)A portion of a circle defined by two radii and an intercepted arc.
