Diamond term is attributed to a shape presented on all cards of the suit "diamonds". Pentagon Definition. That would be “appropriate”. The discussion in my post is about the use of the word “diamond” in the context of a math class, where we expect words to be used with careful definitions. Quadrilateral proofs & angles. In the above figure, the four sides namely AB, BC, CD, DA are parallel and equal. Identifies and draws circles, squares, triangles, ovals (ellipses), and rectangles. It’s too bad we rarely were able to get into that discussion with these students. Learn more. The rotated figure is still a square! But in Geometry they mean the same. Terms in this set (39) Square. A square also fits the definition of a rectangle (all angles are 90°), and a rhombus (all sides are equal length).

In geometry, a shape can be defined as the form of an object or its outline, outer boundary or outer surface. But in Geometry they mean the same. Diamond definition, a pure or nearly pure, extremely hard form of carbon, naturally crystallized in the isometric system. In plane Euclidean geometry, a rhombus (plural rhombi or rhombuses) is a quadrilateral whose four sides all have the same length. Doctor Rick pointed out that the concept of shape should be independent of orientation; that is, rotating a figure can’t really change its shape.

But, as I have seen other times, it appears that the creator of the lesson plan took the standard literally, reading more into it than was intended; that misled the teacher, who then confused the mother who wrote to us. It goes above and beyond that to also have four equal-length sides, but it is still a type of parallelogram. This kind of diamond is 3-Dimensional, so it would be a polyhedron, not a polygon. The Hexahedron is one of the five Platonic Shapes, which are well-known aspects of sacred geometry. So a rhombus by definition, the four sides are going to be equal. A more flexible definition of shape takes into consideration the fact that realistic shapes are often deformable, e.g. Step 3: Area of the diamond = 84 cm2, Identifying-and-Locating-Ordered-Pairs-Gr-5, Reading-and-Writing-Decimals-to-Thousandths-Gr-5.
