Ans:

21. What does a circle look like? How is a circle different from a rectangle?

Ans:

• A circle is a simple, closed shape where every point on the curve is equidistant from a fixed point called the centre. This distance from the centre to any point on the circle is known as the radius. The shape is perfectly round, with no edges or corners.

• A rectangle, on the other hand, is a four-sided polygon with opposite sides that are equal in length and all angles that are right angles (90 degrees). Unlike a circle, a rectangle has straight edges and four corners, or vertices.

Ans:

27. Each of these shapes can be the odd one out.

How is each one odd? Discuss

Ans: Red Shape (Circle within a Square)

• Odd Based on Shape: The red shape is unique because it contains both a square and a circle, whereas all other shapes are singular shapes.

• Odd Based on Colour: It is the only shape that combines two different shapes in one (circle inside a square).

Orange Rectangle

• Odd Based on Shape: The orange rectangle is the only shape that is not equilateral, meaning its sides are not all of equal length.

• Odd Based on Shape Type: It’s the only shape that is not symmetric along both axes (it is symmetric only along its vertical axis).

Blue Triangle

• Odd Based on Corners: The blue triangle is the only shape with three sides and three corners, while the others have four sides.

• Odd Based on Type of Angles: It's the only shape that includes angles less than 90 degrees.

Green Square

• Odd Based on Colour: The green square is the only shape with no additional features (like the circle inside the red square) and is purely one colour.

• Odd Based on Symmetry: It’s the only shape that is perfectly symmetric along both its horizontal and vertical axes without any inner shape or additional elements.

28. To complete the rectangle, tick the appropriate shapes from the left side to fill the gaps in the shape on the right side.

Ans:

Ans:
