The local swimming pool is having a contest and all students are welcome to enter. The pool officials want a new logo that has rotational symmetry with 120⁰ and 240⁰ as its angles of rotation. Draw an entry for the contest.
To create a logo with rotational symmetry, we need to understand what rotational symmetry means. Rotational symmetry is when a shape or design remains the same after a rotation. In this case, the logo needs to have rotational symmetry with angles of rotation at 120⁰ and 240⁰.
To draw a logo with this kind of symmetry, we can start by imagining a shape that has 120⁰ rotational symmetry—such as an equilateral triangle. An equilateral triangle has three equal sides and three equal angles of 60⁰ each.
To begin, draw an equilateral triangle. Make sure the sides are equal in length and the angles are all 60⁰.
Next, find the midpoint of each side. From each midpoint, draw a line segment perpendicular to the corresponding side. These lines should intersect at the center of the triangle.
At the tip of each line segment, draw a smaller equilateral triangle, keeping the sides equal and the angles at 60⁰.
Finally, repeat the previous steps with the new smaller triangles. Find the midpoint of each side, draw a line segment perpendicular to the corresponding side, and then draw even smaller equilateral triangles at the tip of each of these line segments.
Continue this process until you have reached the desired level of detail within the logo, keeping in mind the rotational symmetry with angles of 120⁰ and 240⁰.
Remember, creativity is key. You can experiment with different shapes, colors, and patterns to make your logo more visually appealing and unique.
