Geometric Diagram with Circle and Lines

A clear geometric diagram depicts a rhombus, labeled ABCD, with its diagonals AC and BD intersecting perpendicularly at the central point O. An inscribed circle is shown within the rhombus, perfectly tangent to all four sides, also centered at O. The half-lengths of the diagonals are indicated as 'a/2' for the vertical diagonal (AC) and 'b/2' for the horizontal diagonal (BD). A line segment from the center O to a point H on the circle's circumference is labeled 'h', representing the radius of the inscribed circle. The illustration visually represents the relationship between the diagonals of a rhombus and the radius of its inscribed circle.
