7 columns of dots. center is 1 column of 6 dots. working outward to the left and right of the center column, 2 columns of 4 dots, 2 columns of 2 dots, 2 columns of 1 dot. All lined up in the shape of a rhombus.
Activity 1
Here is a pair of parallel segments that have the same length.
Draw 1 or more segments to create a figure with only 1 line of symmetry.
Here are some other pairs of parallel segments. Draw more segments to make:
a figure with 2 lines of symmetry
a figure with 0 lines of symmetry
If you have time: Here are some other pairs of parallel lines. Draw more segments to create a figure with only 1 line of symmetry.
Activity 2
Here is a field of dots.
Can you connect the dots to create each of the following shapes? If so, draw the shapes. If not, explain your reasoning.
a triangle with only 1 line of symmetry
a quadrilateral with only 1 line of symmetry
a quadrilateral with 2 pairs of parallel sides
a quadrilateral with 1 pair of perpendicular sides
