Identifying Two-dimensional Shapes

T.I.P.S.

Lightbulb

The student must be able to identify two-dimensional figures, including circles, triangles, rectangles, rhombuses, and hexagons. The students must be able to see that a square is a special rectangle. Students must also be able to explain and justify their mathematical ideas and arguments using formal geometric language.

Example

Which of the following shapes is NOT a rhombus? Explain your solution and thinking.

TEKS

1.6 Geometry and measurement. The student applies mathematical process standards to analyze attributes of two-dimensional shapes and three-dimensional solids to develop generalizations about their properties. The student is expected to:

(D) identify two-dimensional shapes, including circles, triangles, rectangles, and squares, as special rectangles, rhombuses, and hexagons and describe their attributes using formal geometric language
