Usually, solid shapes have more than two faces; if that is the case, then the simplest shape we are looking at is a triangular pyramid (both upright and oblique pyramids are considered here).
However, if you're looking for a two-faced solid, then you'll be fresh out of luck, even with non-Euclidean geometry, as you cannot have an equilateral triangle and an isosceles triangle in the same shape (unless you make the isosceles triangle an equilateral one).
Tetrahedron: 4 equilateral triangle faces and 4 vertices.
No- a triangle is a plane figure, not a solid.
A net has two equilateral triangles and 3 rectangles. What solid figure might it make?
yes a triangle is a solid figure
i think it would be a triangle, because usually it has 3 sides. so my opinion is that it is a triangle. Or maybe a square.. because it would be a equilateral 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).
triangle. * * * * * A triangle is not a solid figure. However, a triangular pyramid (tetrahedron) is the correct answer.
There are several: a tetrahedron with 4 equilateral triangles. An 8-sided solid (think of 2 Egyptian pyramids, turn one upside down and put the two square bases together). A 20-sided also has equilateral triangles.
A cube and an equilateral triangle based pyramid
a pyramid, in the sense that most people think of has a square base, with 4 triangle 'sides', which would be 5 faces. A regular tetrahedron has 4 equilateral triangles as faces.
A circle * * * * * On the right lines but a circle is not a solid figure. How about a sphere?
Isosceles TetrahedronA solid with four faces is a tetrahedron. Each of the faces is a triangle. If all the triangles are congruent, you have an isosceles tetrahedron.
