Geometry

We have begun working on geometry in math. We have discussed polygons as a closed figure with at least 3 sides, as well as the names of each figure (from triangles up to octogons). We have also gone through the different quadrilaterals and triangles and the names and attributes of each. It would be beneficial for students to review these at home so they become familiar with the terms and the attributes of these shapes. Here is a list of terms by number of sides:

3- triangles: scalene (no sides equal)

                   Isosceles (2 equal sides)

                   Equilateral (all sides equal)

4- quadrilaterals: trapezoid (1 pair of parallel sides)

                           Parallelogram (2 pairs of parallel sides)

                           Rhombus (2 pairs of parallel sides and all sides equal)

                           Rectangle (2 pairs of parallel sides and all right angles)

                           Square (2 pairs of parallel sides, all sides equal, and all right angles)

5- Pentagon

6- hexagon 

7- heptagon

8- octogon
