Question

shade in and name using the letters in the diagram, the polygon described

1. an isosceles (but not equilateral) triangle 13) a rectangle
2. a regular hexagon 15) a parallelogram

Explanation:

Step1: Recall polygon definitions

An isosceles triangle has two equal - length sides, a rectangle has four right - angles, a regular hexagon has six equal sides and six equal angles, and a parallelogram has two pairs of parallel sides.

Step2: Identify isosceles triangle

For an isosceles (but not equilateral) triangle, we can choose $\triangle EAF$ (answers may vary as long as two sides are equal and all three are not).

Step3: Identify rectangle

For a rectangle, we can consider the four - point combination that forms right - angles. For example, rectangle $ABCD$ (assuming appropriate right - angled intersections based on the circle intersections).

Step4: Identify regular hexagon

For a regular hexagon, we can take hexagon $ABCDEF$ (assuming equal side lengths based on circle intersections).

Step5: Identify parallelogram

For a parallelogram, we can choose parallelogram $EFGH$ (assuming appropriate parallel - side relationships based on circle intersections).

Answer:

1. $\triangle EAF$ (answers may vary)
2. Rectangle $ABCD$ (answers may vary)
3. Hexagon $ABCDEF$ (answers may vary)
4. Parallelogram $EFGH$ (answers may vary)
