Grouping the options:
In order to determine which option does not belong to the group, let's analyze the given options and identify any patterns or similarities among them.
Option 1: Square
Option 2: Circle
Option 3: Triangle
Option 4: Rectangle
Option 5: Pentagon
Shape Classification:
Upon analyzing the given options, we can classify them into different shapes. The shapes include:
1. Square
2. Circle
3. Triangle
4. Rectangle
5. Pentagon
Grouping Similar Shapes:
Upon further inspection, we can see that all the shapes except for the circle have straight sides. The circle, on the other hand, has a curved boundary. Therefore, the circle does not belong to the group of shapes with straight sides.
Conclusion:
After analyzing the given options, we can conclude that the shape that does not belong to the group is the circle. This is because the circle is the only shape among the options that does not have straight sides. Square, triangle, rectangle, and pentagon all have straight sides, while the circle has a curved boundary.
