Description |
Circle |
A circle is a two-dimensional shape that is created by drawing a line that is curved so that its ends meet and every point on the line is the same distance from the center |
Square |
A square is a two-dimensional shape that has four straight sides that are all equal in length, and four right angles (90°) |
Triangle |
A triangle is a two-dimensional shape that has three straight sides and three angles |
Rectangle |
A rectangle is a two-dimensional shape that has four straight sides and four right angles (90°) |
Parallelogram |
A parallelogram is a two-dimensional shape. It has four straight sides where the opposite sides are both equal in length and parallel to each other. |
Rhombus |
A rhombus is a two-dimensional shape. It has four straight sides that are all equal length, and the opposite sides are parallel to each other |
Trapezoid |
A trapezoid (as defined in the US) is a two-dimensional shape that is a quadrilateral with one pair of sides that are parallel |
Trapezium |
A trapezium (as defined in the UK) is a two-dimensional shape that is a quadrilateral with one pair of sides that are parallel |
