Write a short note on enlargement for j a s 2

Answer 1

Enlargement is a transformation in geometry that changes the size of a shape while keeping its shape and proportions the same. It is commonly used in maps, blueprints, and architectural designs to scale up or down the size of a building or plot of land.

Enlargement is achieved by multiplying the coordinates of each point on the shape by a given scale factor. The scale factor can be greater than 1, resulting in an increase in size, or less than 1, resulting in a decrease in size. By using the same scale factor for all points on the shape, the proportions and angles of the shape remain the same.

In practical applications, enlargement is frequently used to create diagrams and plans that accurately represent the size of a real-life object, while still fitting within the constraints of a smaller medium. For example, an architect may need to create a blueprint of a building that is too large to fit on a single piece of paper. By using the enlargement technique, the architect can scale down the dimensions of the building to fit on a smaller blueprint while still preserving its proportions.

Overall, enlargement is a useful concept in geometry and design that allows for accurate representations of objects at different sizes while maintaining their original shape and proportions.
