a quadrilateral such as a square, rhombus, or rectangle
A quadrilateral which has 4 sides
triangle * * * * * A triangle is NOT a 3d shape! A cube.
A shape that has 3 more vertices than a triangle, which has 3 vertices, is a hexagon. A hexagon has a total of 6 vertices. This geometric figure can be regular, with all sides and angles equal, or irregular, with varying side lengths and angles.
An octagon.
hexagon
a square
A polygon with 2 more side than a triangle is a 5 sided pentagon.
One more side.
A triangle has three sides, so a hexagon (a shape with six sides) would have three more sides than a triangle.
A triangle for example has 3 vertices.
If (and only if) the length of each pair of sides is greater than the third side, then it is possible to make a triangle.
If two sides of a triangle have lengths of 5cm and 12cm, then the third side can have any length that's more than 7cm and less than 17cm. If the third side is 13cm, then the triangle is a right triangle.
