Measuring segments:
8. Line AB ; A= -8 B= -6
Answer: Line AB=2
9. Line BD ; B= -6 D=-3
Answer: Line BD= 9
10. Line AD ; A= -8 D= -3
Answer: Line AD= 11
11. Line CE ; C= 1 E= 7
Answer: Line CE=6
Hmmm. Odd, You got #8 right, and missed #9 & #10.
Also #11 is ok.
OH! your right I see my mistake!!
Thanks.
For them it was double negative..
Thanks.
To measure the length of a line segment, you need the coordinates of its endpoints. The length of a line segment is equal to the absolute difference between the coordinates of its endpoints.
Let's go through each example:
8. Line AB with coordinates A (-8) and B (-6). To find the length of AB, you subtract the x-coordinate of A from the x-coordinate of B: -6 - (-8) = -6 + 8 = 2. Therefore, Line AB has a length of 2 units.
9. Line BD with coordinates B (-6) and D (-3). To find the length of BD, you subtract the x-coordinate of B from the x-coordinate of D: -3 - (-6) = -3 + 6 = 3. Therefore, Line BD has a length of 3 units.
10. Line AD with coordinates A (-8) and D (-3). To find the length of AD, you subtract the x-coordinate of A from the x-coordinate of D: -3 - (-8) = -3 + 8 = 5. Therefore, Line AD has a length of 5 units.
11. Line CE with coordinates C (1) and E (7). To find the length of CE, you subtract the x-coordinate of C from the x-coordinate of E: 7 - 1 = 6. Therefore, Line CE has a length of 6 units.
Remember, when measuring the length of a line segment, you subtract the x-coordinate of one endpoint from the x-coordinate of the other endpoint.
