Exercise 1.5
Table 3: Examples of Shape Sequences
1. Can you recognise the pattern in each of the sequences in Table 3?
Ans:
(a) Regular Polygons: Examples include triangle, quadrilateral, pentagon, and hexagon. In these shapes, the number of sides increases by 1 with each step, starting from 3. This forms a continuous number sequence where each polygon has one more side than the previous one.
(b) Complete Graphs
The number of lines in the sequence is as follows:
For K2 = 1, K3 = 3, K4 = 6, K5 = 10, and K6 = 15. The resulting series is 1, 3, 6, 10, 15,…. This forms a triangular number sequence, where each term represents the total number of lines that can form a triangle. Triangular numbers are generated by adding consecutive natural numbers, making this sequence grow in a predictable pattern.
(c) Stacked Squares:
The number of small squares in each layer follows the pattern: 1, 4, 9, 16, 25, and so on. This sequence represents square numbers, where each term is the result of squaring a natural number ($1^{2}$, $2^{2}$, $3^{2}$, etc.).
The arrangement visually forms a perfect square, showing how the number of small squares increases as the layers grow, perfectly fitting into a square grid. Hence, it’s a clear representation of a square number sequence.
(d) Stacked Triangles:
The number of small triangles in each layer follows the pattern:
Thus, it is also a square number sequence represented through triangular formations.
(e) Koch Snowflake:
Number of sides in each becomes 4 times.
The number of sides in each increases by a factor of 4.
2. Try and redraw each sequence in Table 3 in your notebook. Can you draw the next shape in each sequence? Why or why not? After each sequence, describe in your own words what is the rule or pattern for forming the shapes in the sequence.
Ans: (a) Regular Polygon
A polygon with 11 sides, is known as a hendecagon.
(b) K6
The image shows a complete graph with 7 vertices (K7), where every point is connected to every other point with straight lines.
(c) Stacked Squares
The total number of squares is 6 × 6 = 36. This calculation represents a perfect square, showing how the number of small squares forms a 6x6 grid.
(d) Stacked Triangles
The total number of triangles is 1 + 3 + 5 + 7 + 9 + 11 = 36. This sum represents the sequential addition of odd numbers, resulting in the total number of triangles in the arrangement.
(e) Koch Snowflake
The shape is a Koch snowflake, created by repeatedly adding triangular bumps to each side of an equilateral triangle.
