Equilateral Stone Arc

Confinement along the parquet had yielded standard order, yet the glazed ceramic planter saucer required immediate survey. Resting on its terracotta brim were three smooth black river pebbles, huddled in a clump that left the opposite rim vacant. Protocol forbade such lop-sided mass distribution. Planting my mechanical stance upon the cool ceramic rim, I paused to calculate the circumference. With measured lateral nudges from the flat face of my beige blade, I guided each stone around the curve until they formed an unyielding equilateral triangle across the saucer. Geometric balance holds firm.
