Domain-specific¶
- Isosceles Trapezoid
- An isosceles trapezoid, under the inclusive convention used here, is a convex Euclidean quadrilateral with a chosen pair of opposite parallel sides, called bases, whose perpendicular midpoint line reflects the whole figure onto itself.
This sourceOfficial problem and solutions for the proper case, including midpoint reflection, cyclicity, Ptolemy, and the (1/3) base ratio.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
