The image displays a geometric figure. **Options:** Not provided in the image. **Other Relevant Text:** * Length of segment AB = 2cm. * Length of segment BC = 2cm. **Mathematical Formulas/Chemical Equations:** None present in the image. **Table Content:** No tables present in the image. **Chart/Diagram Description:** * **Type:** Geometric figure. * **Main Elements:** * **Points:** Three labeled points: A, B, and C. * **Lines/Segments:** * A vertical line segment AB, labeled with a length of 2cm. * A horizontal line segment BC, labeled with a length of 2cm. * **Shapes:** * The angle at point B, formed by segments AB and BC, appears to be a right angle (90 degrees). * Three curved arcs are present, forming three intersecting "leaf-like" or "petal-like" shapes. * One arc originates from point A and curves towards the center of the figure. * One arc originates from point B and curves upwards and to the right, towards the center. * One arc originates from point C and curves upwards and to the left, towards the center. * These three arcs intersect at a common central point within the figure. * Three distinct regions formed by these intersecting arcs are shaded in blue. * **Labels and Annotations:** * The label "2cm" is placed next to segment AB, indicating its length. * The label "2cm" is placed next to segment BC, indicating its length. * **Relative Position and Direction:** * Point B is located at the bottom-left corner of the figure. * Point A is positioned directly above point B. * Point C is positioned directly to the right of point B. * The shaded regions converge towards a central point, forming a tri-lobed or three-petal arrangement. One shaded region is primarily between A and the center, one between B and the center, and one between C and the center.
