WGU MATH D125 COMPREHENSIVE EXAM
QUESTIONS AND CORRECT ANSWERS
STUDY GUIDE
●● 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
