                    1.  Check for right angles in a book, window, and any other object. Write the names of

                       objects where you find right angles.

                   2.  identity the types of angles (acute, obtuse and right) in the following letters:


                       a.                  b.                  c.                  d.                 e.




                   3.  In the yoga poses given below, mark the acute angles in red, right angles in green,
                       and obtuse angles in blue.












                   4.  Draw a line to make an angle, as directed, using each given line in the following grid.




















                           Acute angle               Obtuse angle             Obtuse angle             Right angle

                Simple closed figures made with only line segments are called polygons. These are
                polygons:
