Answer: (5,3)
Step-by-step explanation:
1. Let's say you opened your laptop and positioned the screen so it's exactly at 90°—a right angle—from your
keyboard. Now, let's say you could take the screen and push it all the way down beyond 90°, until the back of the
screen is flat against your desk. It looks as if the angle disappeared, but it hasn't. What is the angle called, and what
is its measurement?
A. Straight angle at 180°
B. Linear angle at 90°
C. Collinear angle at 120°
D. Horizontal angle at 180°
2. What is defined below?
__________: a portion of a line bounded by two points
A. arc
B. axis
C. ray
D. segment
3. Given ⃡ and ⃡ intersect at point .
Which conjecture is always true about the given statement?
A. =
B. ∠ is acute.
C. ⃡ is perpendicular to ⃡
D. , , , and are .
4. The figure shows lines r, n, and p intersecting to form angles numbered 1, 2, 3, 4, 5, and 6. All three lines lie in the
same plane.
Based on the figure, which of the individual statements would provide enough information to conclude that line r is
perpendicular to line ? Select ALL that apply.
∠2 = 90°
∠6 = 90°
∠3 = ∠6
∠1 + ∠6 = 90°
∠3 + ∠4 = 90°
∠4 + ∠5 = 90°
5. Match each term with its definition.

The set of all points in a plane that are a fixed distance from a point called the center.
A portion of a line that starts at a point and continues forever in one direction.
Lines that intersect at right angles.
A specific location, it has no dimension and is represented by a dot.
Lines that lie in the same plane and do not intersect
perpendicular lines
angle
line segment
