常见错误

❌ 错误:I bought an icosahedron toy for my kid, it's a ball.
✓ 正确:I bought a toy shaped like an icosahedron for my kid, it's a geometric model.

错误用法中误将 icosahedron 等同于普通球体,正确用法应强调其作为几何形状的特性,避免混淆日常物体。

❌ 错误:The icosahedron have twenty sides.
✓ 正确:The icosahedron has twenty faces.

错误用法中使用了错误的动词形式和术语 'sides',正确用法应用单数动词 'has' 和几何术语 'faces' 来描述二十面体的面数。

近义词辨析

polyhedron

polyhedron 是泛指任何多面体的通用术语,而 icosahedron 特指由二十个面组成的多面体,更具具体性。

A cube is a polyhedron, but an icosahedron has more faces than a cube.

dodecahedron

dodecahedron 指十二面体,由十二个五边形面组成,而 icosahedron 是二十面体,由二十个三角形面组成,两者在面数和形状上不同。

In geometry class, we compared the dodecahedron and icosahedron for their symmetries.
