Maths Elementary Shapes part 20 (Questions: Quadrilateral) CBSE Class 6 Mathematics VI

## TL;DR

Learn about the properties of quadrilaterals and how different shapes can be thought of as special versions of each other.

## Key Insights

• 😆 A square satisfies all the properties of a rhombus, rectangle, and parallelogram, making it a special version of each.
• 😚 To be considered a polygon, a shape must be a closed curve and made up of only line segments.
• 💠 Drawing a rectangle inside an octagon involves joining specific vertices of the octagon.

### Q: Can a square be thought of as a special rhombus?

Yes, a square can be considered a special rhombus because it satisfies all the criteria of a rhombus, including equal sides. Additionally, a square has all angles equal, which distinguishes it from a regular rhombus.

### Q: Can a square be thought of as a special rectangle?

Absolutely. A square meets all the conditions to be a rectangle, including equal angles of 90 degrees and opposite sides being parallel. In fact, a square has additional features, such as equal diagonals, that make it a special kind of rectangle.

### Q: Can a rectangle be thought of as a special parallelogram?

Yes, a rectangle can be considered a special parallelogram because it meets the criteria of a parallelogram, such as having opposite sides parallel and equal lengths. As a rectangle, it also has the extra feature of having all angles equal.

### Q: Are the shapes shown in the images polygons?

The first shape shown is not a polygon because it is not a closed curve. It is open at certain points, which violates the criterion of being a closed curve. The second shape is also not a polygon because it is not made up of only line segments, but rather curved segments.

## Summary & Key Takeaways

• This video teaches the properties of different types of quadrilaterals, such as squares, rectangles, and parallelograms.

• It explains how a square can be considered a special rhombus, rectangle, and parallelogram, satisfying all the criteria of each shape.

• The video also demonstrates how to draw a rectangle inside an octagon by joining specific vertices.
