”Repetition” refers to the recurrence or alternation of design elements such as lines, colors, shapes, or patterns. Repetition creates rhythm and unity in a design, providing a sense of consistency and harmony. It is an effective technique to emphasize particular elements and establish a visual connection throughout the design. This principle is widely used in both fine arts and commercial design to create cohesive and balanced work.
In the adjoining figure, \( AP = 1 \, \text{cm}, \ BP = 2 \, \text{cm}, \ AQ = 1.5 \, \text{cm}, \ AC = 4.5 \, \text{cm} \) Prove that \( \triangle APQ \sim \triangle ABC \).
Hence, find the length of \( PQ \), if \( BC = 3.6 \, \text{cm} \).
In the adjoining figure, $\triangle CAB$ is a right triangle, right angled at A and $AD \perp BC$. Prove that $\triangle ADB \sim \triangle CDA$. Further, if $BC = 10$ cm and $CD = 2$ cm, find the length of AD.
