Does the shape of the pentagon change if we gently push one of its sides? How does this change the angles?

Correct Answer

Yes, the shape of the pentagon changes if we gently push one of its sides.

Pentagons, like rectangles, are not rigid shapes.

When pushed, the angles change — some angles become larger (more obtuse) and some become smaller (more acute).

The shape deforms and is no longer a regular pentagon.

Explanation

The chapter demonstrates that pentagons, like other polygons with more than three sides, are not rigid and can deform when pushed.

Solution Steps

  1. Pentagons are not rigid shapes and can deform when pushed.

  2. When pushed, the angles change — some become larger (more obtuse) and some become smaller (more acute).

  3. The shape deforms and is no longer a regular pentagon.
