Answer Key/Rubric
- Ray
- Parallel lines
- Obtuse angle
- There are 2 acute angles in the trapezoid.
- Lines may vary in location that are drawn perpendicular to
, one example is shown below:
- Questions have more than one possible answer; acceptable answers may include:
; A ray has a starting point, and then continues on forever in one direction.
; A right angle measures exactly 90 degrees, and is represented in a drawing by a box in the corner.
; A line continues on in both directions, with no end, represented by the arrows at the end.
; An acute angle measures more than 0 degrees, but less than 90 degrees.
; A line segment has a definite beginning and end.
; An obtuse angle measures more than 90 degrees, but less than 180 degrees.
- Answers and explanations might include, but are not limited to:
Which set of lines is parallel?
The lines that are parallel are line CD and line XY. They are parallel because no matter how far you extend them in either direction they will not cross/touch each other.
Which angle is acute?
Angle SRT is an acute angle. It is acute because its measure is great than 0° and less than 90°.
Which set of lines is perpendicular?
The lines that are perpendicular are line AB and line CD. They are perpendicular because they intersect at a right angle that is shown by the square at the intersection point.
