A triangle.
A hexahedron is a three-dimensional geometric shape having six sides; a hexagon is a two-dimensional six-sided shape.
A pentagon has fives sides, or if you mean a three dimensional shape, a pyramid has five sides, four triangular and one square.
Any geometric shape that has more than three sides.
A geometric shape that has 11 sides is called a "hendecagon" or "undecagon." Both terms are acceptable.
An octagon has 8 sides.
Octagon
The geometric shape that has four unequal sides is called a trapezium. It is also known as a general irregular quadrilateral.
If you have the length of each of the three sides of a triangle, you can find the perimeter of (the distance around) the triangle by adding the length of the sides. Their sum will be the perimeter of this geometric shape.
Yes and it has 3 sides.
A triangle is a shape that has 3 sides and 3 corners. It is a three-sided polygon, which is a plane shape bounded by three straight lines.
A geometric shape with only one set of parallel sides is a trapezoid.
The Earth is NOT a geometric shape because the Earth is not bounded; meaning it does not have sides or measurable depth, height, or width.
