Domain-specific¶
- Isosceles Trapezoid
- For unequal positive base lengths, the axis condition is equivalent to equality of the legs, equality of the diagonals, and equality of the angles at each base.
This sourceAuthoritative mathematical reference for height, area, and equal diagonal formulas in a proper isosceles trapezoid; the equal-base edge case and coordinate equivalence are derived explicitly in this article.
- For unequal positive base lengths, the axis condition is equivalent to equality of the legs, equality of the diagonals, and equality of the angles at each base.
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.
