a triangle
A triangle has three faces. In geometry, a face refers to a flat surface of a solid shape. Since a triangle is a two-dimensional shape with three sides, it has three faces. Each side of the triangle forms one of its three faces.
A triangle has only one face and, not surprisingly, its shape is a triangle.
A regular dodecahedron, for example. Each face is a regular pentagon so no face has parallel sides. However, the edges on opposite faces are parallel to one another.
A cylinder has a circular face at each end, and a rectangular face folder around the middle. The only edges are the edges of the circular ends.
A triangle has one face, three vertices and three edges.
a pyramid where each face is the shape of a triangle
Oh, dude, an equilateral triangle has 3 vertices, 3 faces (which are also the sides), and 3 edges. It's like the most balanced shape ever, so chill.
3 vertices, 3 edges and 1 face.
draw the different faces of these 3 D objects.Label the shape of each face
A nonagon is nine sided. So, the base would have 9 sides and each face would be triangle. 18 edges would be my answer.
