What we have learnt
- Geometry involves the study of shapes, sizes, and properties of figures and spaces.
- Angles can be classified into several types: acute, right, obtuse, straight, reflex, and complete.
- Congruent triangles are defined by specific criteria like SSS, SAS, ASA, AAS, and RHS.
Key Concepts
- -- Point
- A location in space with no length, breadth, or thickness.
- -- Line
- A straight one-dimensional figure extending infinitely in both directions.
- -- Angle
- The figure formed by two rays that share a common endpoint.
- -- Triangle
- A polygon with three edges and vertices.
- -- Congruence
- A condition where two geometric figures are identical in shape and size.
