Question: 1.15.
Summative Assessment 15 - Assignment
a) How many lines of reflective symmetry does the following shape have?
1. **Problem Statement:**
Determine the number of lines of reflective symmetry for a shape formed by overlapping two congruent diamonds (a 4-point star).
2. **Understanding the Shape:**
The shape is a 4-point star created by overlapping two congruent diamonds.
Each diamond has 2 lines of symmetry (vertical and horizontal).
3. **Lines of Symmetry in the 4-Point Star:**
When two diamonds overlap to form a 4-point star, the resulting figure has lines of symmetry along:
- The vertical axis
- The horizontal axis
- The two diagonals
4. **Counting the Lines:**
Therefore, the 4-point star has 4 lines of reflective symmetry.
5. **Summary:**
The shape has $$4$$ lines of reflective symmetry.
