Hello Students,

As we continue with our unit on Geometric Shapes I want you to remember what we learned in class today.  We reviewed our lesson on Quadrilaterals.  A quadrilateral is a shape with 4 sides.

We also began our study of polygons.  A regular polygon is a shape in which all angles and sides are equal.  An irregular polygon is any polygon that is not a regular polygon. A polygon whose sides are not all the same length or whose interior angles do not all have the same measure.  We also learned that polygons can be both two-dimensional and three-dimensional.  We will focus more on this next math lesson.

Here are four shapes. 

Calculate the area of each shape and state if you think it is a regular polygon or an irregular polygon.  The first person to show me the correct answers for each shape after the morning bell will get a surprise from me.

After you have completed this check your skills on geometric shapes here. 

Be sure to remember this post and refer to it as you study for our Geometry test at the end of this unit.

Happy problem-solving! J

Ms. Greco
