My daughters homework,Alphabet Polygons,her teacher gave a alphabet chart A-I first row, J-R second row, s-z third row the question 1. you can make 1 or 2 polygons of some of the letters by drawing just one more line segment, which letters are they>?

Ask yer to study this page, especially about the triangle and quadrilateral.

To get her started --
Draw a horizontal line under A to make a triangle.
B, C, and D won't work because they have curves.

To determine which letters can form one or two polygons by drawing just one more line segment, you will need to visualize the shapes formed by connecting the existing line segments of each letter.

Here's how you can approach this task:

1. Locate the alphabet chart provided by the teacher. It consists of three rows: A-I, J-R, and S-Z.

2. Begin with the first row of the chart (A-I). Look at each letter individually and imagine connecting its existing line segments with one additional line segment.

3. For example, take the letter A. It already has two line segments: one diagonal line and one horizontal line. To form a polygon, you would need to connect these two line segments with one more line segment.

4. By visualizing this, you will see that you can form a triangle (polygon) using the existing diagonal line as one side, the existing horizontal line as another side, and the additional line segment as the third side.

5. Repeat this process for each letter in the A-I row, visualizing how you could connect the existing line segments with one more line segment to form a polygon. Take note of the letters that can form one or two polygons.

6. Move on to the second row (J-R) and repeat steps 3-5 for each letter in this row, identifying the letters that meet the criteria.

7. Finally, move to the third row (S-Z) and follow the same process to find the remaining letters that can form one or two polygons.

By carefully examining each letter and visualizing the additional line segment needed, you should be able to determine which letters can form one or two polygons.
