isosceles

A sort of isosceles triangle is formed, which will eventually collapse.

Something about isosceles triangles that I learned the year before at Iqra.

Evenly spaced branches reached out from a trunk twisted into gentle contrapposto, its clusters of spring green foliage suggesting the outline of an isosceles triangle.

The first warm evenings brought the summer triangle, a brilliant isosceles made up of the stars Vega, Deneb and Altair, to the eastern edge of my yard.

That’s when an equilateral triangle becomes an isosceles, often with one person isolated at the farthest point.
