To solve the problem of drawing the lines of symmetry for each shape, we need to identify and draw all the lines that divide each shape into two identical halves. Here's a step-by-step explanation for each shape:
---
1. Rectangle
-
Shape: A rectangle has two lines of symmetry.
-
Lines of Symmetry:
- One vertical line passing through the midpoint of the longer sides.
- One horizontal line passing through the midpoint of the shorter sides.
---
2. Triangle
-
Shape: An equilateral triangle (all sides equal) has three lines of symmetry.
-
Lines of Symmetry:
- Each line passes through one vertex and the midpoint of the opposite side.
---
3. Heart
-
Shape: A heart typically has one line of symmetry.
-
Line of Symmetry:
- A vertical line passing through the center of the heart.
---
4. Star
-
Shape: A regular star (five-pointed star) has five lines of symmetry.
-
Lines of Symmetry:
- Each line passes through one point of the star and the midpoint of the opposite side.
---
5. Trapezoid
-
Shape: The trapezoid shown is an isosceles trapezoid (the non-parallel sides are equal).
-
Line of Symmetry:
- One vertical line passing through the midpoints of the parallel sides.
