1. The point that divides a segment into two congruent segments
A point, ray, line, line segment or plane that
intersects a segment at its midpoint

2. T TS
RT TS
43.4
43.4 units

3. 3x x + 3
x x 5
3x (5)
13 units

4. JK = KL 8 - 3x = 2x + 5 8 = 5x + 5 3 = 5x 3/5 = x KL = 2x + 51 5
or 31/5 units

6.
1 4
M(1, 4)
(5, 2)

7. x2 - x y2 - y1 or
AB = √(x1 - x2)2 + (y1 - y2)2

8. (x2, y2)
(x1, y1)
x2 - x y2 - y1 50
√25 × √2
5 × √2 or just 5√2
5√2 is the exact answer
7.071
Pre AP & AP math
round to 3 decimals
7.071 is an approximate
answer

9. exact and
GH = √(x2 - x1)2 + (y2 - y1)2
GH = √(-3 - 5)2 + (6 - (-1))2
GH = √(-8)2 + (7)2
GH = √
GH = √ (exact answer)
GH ≈ (approx. ans.)
