The solid figure that has 4 flat surfaces that are triangles is a tetrahedron. A tetrahedron is a polyhedron with four triangular faces, six straight edges, and four vertex corners. Each of the four faces of a tetrahedron is an equilateral triangle, making it a regular polyhedron.
No. Gas planets do not have solid surfaces.
This is an impossibility. If it is a solid figure then it will have more than 1 surface. If it has only 1surface and it is a solid, then it must be a sphere, but the surface of a sphere is not flat is it? By using the word 'solid' then by definition, it is three dimensional and has thickness. A cylinder has no vertices , but it has 2flat surfaces. A vertex is a point where three lines meet, such as on a pyramid, which has 4 vertices. Have I forgotten something or is this a 'trick' question?
A plane
A solid shape that can slide is a cube. Its flat surfaces allow it to easily slide along a surface.
The four outer planets (Jupiter, Saturn, Uranus, Neptune) do not have solid surfaces because they are predominantly composed of gases and liquids. These planets are known as gas giants or ice giants due to their large size, thick atmospheres, and lack of a solid surface for landing.
the flat surfaces of a solid figure are the
Figures are not solid.
a decagon
A net has two equilateral triangles and 3 rectangles. What solid figure might it make?
sides of the solid figure
All solid figures have length, width and height and, conversely, if a figure has length, width and height then it is a solid figure.
A sphere.
Tetrahedron.
rhombus
Pyramid
trapezoids, parallelograms, and hexagons
A square pyramid.
