What is the slope of a horizontal line?
Answer: 0
A horizontal line has no vertical change (rise = 0), so slope = rise/run = 0.
The midpoint of a segment with endpoints (2, 4) and (8, 10) is:
Answer: (5, 7)
Midpoint = ((2+8)/2, (4+10)/2) = (10/2, 14/2) = (5, 7).
Two vertical angles are formed when two lines intersect. If one angle measures 65°, the vertical angle measures:
Answer: 65°
Vertical angles are always congruent, so both measure 65°.
What is the distance between the points (0, 0) and (3, 4)?
Answer: 5
Distance = √(3² + 4²) = √(9 + 16) = √25 = 5.
A circle has the equation x² + y² = 25. What is its radius?
Answer: 5
In the standard form x² + y² = r², we have r² = 25, so r = √25 = 5.
Which statement is true about a rectangle?
Answer: Opposite sides are parallel and equal in length
A rectangle has opposite sides that are both parallel and equal, with all four angles measuring 90°.
Point A is at (1, 2) and point B is at (7, 10). What is the length of segment AB?
Answer: 10
Length = √((7−1)² + (10−2)²) = √(36 + 64) = √100 = 10.
