a rectangle
The description given fits that of a triangle.
A net for the 3D shape.
No because it is flat 2d shape with 4 equal sides
SQUARE
A tetrahedron is a solid figure with four flat surfaces that are triangles. Each face of a tetrahedron is a triangle, making a total of four triangular faces in the shape.
That would be a triangle.
No. A triangle is a two-dimensional figure. It has only length and width, but not thickness. It's a flat shape that can be drawn on a piece of paper, whereas solids are 3-dimensional (for example, a pyramid).
Solid.
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 rectangle
A tetrahedron.
Cylinder
rectangle
A polyhedron.
The shape that looks like a triangle with a flat top is called a trapezoid. A trapezoid is a quadrilateral with at least one pair of parallel sides. In this case, the parallel sides are the top and bottom of the trapezoid, giving it the appearance of a triangle with a flat top.
shapes can`t be solids. You can say that a shape is a triangle but u can`t say that a triangle is a solid. shapes are 2D unless your talking about the face of a 3D object
