Answer:
Line m is not parallel to Line n.
Line m is perpendicular to Line k
Step-by-step explanation:
1. Calculate slopes of n and m. N = -2 and M = -7/4. The two slopes aren't the same thus they are not parallel
2. Slope of m = -7/4 and k = 4/7. By definition of perpendicular these two fit the description. (to be perpendicular, k = -1/m
Answer:
E is the same distance from A and B. ⇒ D
Step-by-step explanation:
<em>Let us explain the meaning of perpendicular bisector</em>
If line m is the perpendicular bisector of line n, then
- line m intersect line n at the mid-point of line n
- They form 4 right angles around this mid-point
∵ Line CD is the perpendicular bisector of segment AB
∴ Line CD intersects segment AB at the mid-point of AB
∵ Line CD and segment AB intersected at point E
→ That means E ∈ CD and E ∈ AB
∴ Point E is the mid-point of line AB
∴ Point E divides line AB into 2 equal parts
→ That means point E is at the same distance from points A and B
∴ E is the same distance from A and B.
