D127 WGU Exam Questions with 100%
Correct Answers
vertical line
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.
reflex angle
angles greater than 180 degrees
congruent
Figures that have the same size and shape
angle
The amount of rotation needed to make one line segmant, ray, or line identical with another
line segment, ray r line.
vertex
A point where two line segments meet to form an angle.
isosceles trapezoid
Quadrilateral with one pair of parallel opposite sides (the bases) and another pair of equal
opposite sides.
trapezoid
Quadrilateral with one pair of parallel opposite sides.
diagonal
A line segment with vertices as endpoints that is not an edge.
, line
A straight one-dimensional figure that extends infinitely in both directions.
y-axis
The vertical line that passes through the origin on a coordinate plane.
ray
A line with a single endpoint (or point of origin) that extends infinitely in the other direction.
right angle
An angle of 90°.
regular polygon
A polygon with equal sides and equal angles.
hypotenuse
The largest side of a right triangle, opposite the right angle.
kite
Quadrilateral with two sets of adjacent equal sides and one set of equal opposite angles.
perpendicular
Describes lines intersecting each other to form a 90 degree, or right, angle.
complementary angles
Two angles whose sum is equal to 90°.
origin
