Apex (geometry) - Wikipedia
In an isosceles triangle, the apex is the vertex where the two sides of equal length meet, opposite the unequal third side. [1] In a pyramid or cone, the apex is the vertex at the "top" (opposite the base). In a pyramid, the vertex is the point that is part of all the lateral faces, or where all the lateral edges meet. [2]
Apex - Math.net
An apex is the highest point (relative to the base of a figure) of certain 2D and 3D figures. More specifically, the term apex is usually used to refer to the highest vertex opposite the base of a geometric figure.

3 天之前 · The common polygon vertex at the top of a pyramid or the vertex of a cone is also called an apex. The vertex of an isosceles triangle having angle different from the two equal angles is called the apex of the isosceles triangle.
Properties of Isosceles Triangles | Brilliant Math & Science Wiki
An isosceles triangle is a triangle that has (at least) two equal side lengths. If all three side lengths are equal, the triangle is also equilateral. Isosceles triangles are very helpful in determining unknown angles. In an isosceles triangle, the two equal sides are called legs, and the remaining side is called the base.

Apex|Definition & Meaning - The Story of Mathematics
A pyramid in geometry is a polyhedron composed by joining a polygonal base and a point, named the apex. Per apex and base edge form a triangle named a lateral face. It is a conic entity with a polygonal base. an n-sided base of a pyramid has n + 1 vertices, 2n edges, and n + 1 faces.
