∴ AB = 20
BC = 21
and (20 – r) + (21 – r) = 29
or, 2r = 41 – 29
⇒ r = 6 cm

There are many ways to define intelligence, but generally it refers to the ability to acquire and apply knowledge, think abstractly, reason logically, solve problems, and adapt to new situations. Intelligence can be measured through various tests and assessments, such as IQ tests, which typically assess cognitive abilities such as verbal and mathematical reasoning. However, intelligence is a complex and multi-faceted concept, and different types of intelligence, such as emotional intelligence or creative intelligence, may not be fully captured by traditional IQ tests. Additionally, intelligence can be influenced by both genetic and environmental factors, and may vary across different individuals and cultures.
