Samacheer Kalvi Class 4 Maths Solutions Term 3 Chapter 1 Geometry InText Question

Question 1. Complete the patterns using the given shapes and shade with your own colour.
(i)

Answer:

In simple words: This pattern is made of small petal-like shapes that curve around a center point. To complete it, we add more of these shapes until they form a full circle, making sure to shade them in. Look at how each petal is angled to keep the pattern even.

🎯 Exam Tip: Observe the symmetry and rotation of the existing pattern to predict how it should continue. Each repeating part usually has a consistent angle or placement.

(ii)

Answer:

In simple words: This pattern shows small circles linked together in a line, forming a chain. To complete the pattern, we extend this chain until it forms a full, closed circle, filling all the circles with shade. The circles link together to make a continuous loop.

🎯 Exam Tip: For patterns with repeating elements, count the existing parts and determine how many more are needed to complete the geometric shape (like a full circle or square).

(iii)

Answer:

In simple words: This pattern uses one leaf-like shape. To complete it, we repeat this shape four times, turning it each time, so it forms a full flower. All four parts are then shaded. This makes a symmetrical and balanced design.

🎯 Exam Tip: Look for the central point of rotation or reflection when a single shape is repeated to create a larger symmetrical pattern.
