Interpreting the Answer Key 🗝️
The Answer Key for the Measuring Segments Worksheet serves as a critical resource for both teachers and students. It provides the correct answers to the problems posed in the worksheet, allowing students to check their work. However, it's not just about providing the answers; understanding the reasoning behind each solution is equally important.
Common Problems and Their Solutions
Here are some common types of problems found in the Measuring Segments Worksheet and an explanation of how to solve them:
-
Distance Between Two Points:
- Problem: Given two points, A(1, 2) and B(4, 6), find the length of segment AB.
- Solution: Use the distance formula:
[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} ] Plugging in the coordinates:
[ d = \sqrt{(4 - 1)^2 + (6 - 2)^2} = \sqrt{3^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5 ]
-
Midpoint of a Segment:
- Problem: What is the midpoint of segment AB if A(2, 3) and B(6, 7)?
- Solution: Use the midpoint formula:
[ M = \left( \frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2} \right) ] Thus,
[ M = \left( \frac{2 + 6}{2}, \frac{3 + 7}{2} \right) = (4, 5) ]
-
Measuring Length on a Number Line:
- Problem: Measure the distance between points -3 and 2 on a number line.
- Solution: The distance can be calculated as:
[ d = |x_2 - x_1| = |2 - (-3)| = |2 + 3| = 5 ]
