Planimetrics - practice problems

The planimetrics study plane measurements, including angles, distances, and areas. In other words - measurement and calculation of shapes in the plane. Typical problems involve finding the perimeter and area of plane shapes.

Planimetry is a subfield of geometry that focuses exclusively on plane figures (circle, triangle, quadrilateral) and their:
- Mutual positions (perpendicularity, parallelism),
- Metric properties (circumference, area),
- Construction tasks (using compasses and ruler).

Example:
- Planimetry: Calculation of the area of ​​a circle S = π r2 .
- Stereometry: Calculation of the volume of a sphere V = 43π r3 .

Planimetry is therefore a part of geometry that is limited to two-dimensional figures.
