Math Problem Statement
Which two segments in the drawing above are most likely parallel?
Solution
To determine which two segments are most likely parallel, we need to calculate the slopes of the line segments and compare them. If two segments have the same slope, they are parallel.
Step 1: Identify coordinates of endpoints
From the graph:
- AC: ,
- BD: ,
- FH: ,
- JG: ,
Step 2: Calculate slopes
The formula for slope () is:
-
AC:
-
BD:
-
FH:
-
JG:
Step 3: Compare slopes
- AC has a slope of .
- BD and FH both have a slope of .
- JG has a slope of .
Step 4: Conclusion
Since BD and FH have the same slope (), they are parallel.
Final Answer:
BD and FH
