Two-dimensional.
NO!!! A triangle is a 2-dimensional shape of three sides; archaically a 'trigon'. A polyhedron is a 3-dimensional solid of many sides.
A three-sided, two-dimensional polygon is called a "triangle".
An isosceles triangle.
The analogy for "square: triangle" is "cube: tetrahedron." Just as a square is a two-dimensional shape with four equal sides, a triangle is a three-dimensional shape with three vertices. Similarly, a cube is a three-dimensional shape with six equal square faces, while a tetrahedron is a three-dimensional shape with four triangular faces. Both pairs represent geometric shapes with increasing dimensions and different characteristics.
Two-dimensional shapes are shapes that are flat on the page, such as a square, circle, rectangle, triangle, etc. In contrast, some examples of three-dimensional shapes are cube, sphere, prism, pyramid, etc.
No. A triangle is a two-dimensional object, therefore it is not three-dimensional.
square and triangle
No. A triangle can be a two-dimensional object whereas a pyramid must be three-dimensional (with sides that are sloped).

There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but not a volume.

A two-dimensional shape with three sides is a triangle. A three-dimensional shape with three faces is a cylinder.
A three-sided, two-dimensional polygon is called a "triangle".

There is none because a triangle is a 2D shape -------------------------------------------------------------------------------- There is not one. Triangles are two dimensional, volume is three dimensional, a triangle can therefore have an area but not a volume.
they are two dimensional shapesthey are trianglesthey have three sidestheir interior angles add up to 180 degreestheir exterior angles add up to 360 degreesthey have at least two sides of different lengthsRight triangle: three sided two dimensional shape with one right angleScalene triangle: three sided two dimensional shape with three sides of different lenghtsBeing Scalene and being Right are not mutually exclusive. A Scalene triangle can also be a Right triangle, and vice versa.
