1. Measurement and calculation: Geometric knowledge can help us to measure and calculate, such as measuring the area of a room and calculating the volume of an object. By using geometric principles and methods, we can estimate and calculate various sizes and distances more accurately.

2. Architectural design and decoration: Geometric knowledge is essential in architectural design and decoration. Architects and designers need to use geometric principles to calculate the size, angle and proportion of buildings to ensure the structural stability and aesthetics of buildings.

3. Navigation and positioning: Geometric knowledge plays an important role in navigation and positioning. Using geometric principles, we can determine our position, calculate the shortest path and direction, and find the destination.

4. Art design: Geometry knowledge is also widely used in art design. Artists and designers can use geometric shapes and patterns to create beauty and balance, such as symmetry, proportion and geometric figures in painting, sculpture and graphic design.

5. Engineering technology: Geometry knowledge is essential in the field of engineering technology. Engineers and technical experts need to use geometric principles to calculate the motion, mechanics and stability of objects, and design and manufacture various mechanical equipment and structures.

In short, junior high school mathematics and geometry knowledge are widely used in daily life, whether in the fields of measurement, architecture, navigation, art or engineering, it is inseparable from the support of geometric principles and methods. By studying and applying geometry knowledge, we can better understand and solve problems in daily life.
