Symmetry is a concept that occurs across many dimensions, and this guide dives into the definition of the topic and its related real-world problems. Visually, symmetry can be studied in two and three dimensional formations, as well as in closed or curved circles.

• Explore the concept of two-dimensional symmetry including its definition and examples
• Investigate three-dimensional plane symmetry and determine the order
• Understand rotational symmetry in three dimensions through questions and example
• Discover the symmetrical properties of circles including the perpendicular bisector, equidistance of chords from the center, and more
• Study different angle relationships within circles such as the right angle in a semicircle, the doubling of the angle at the center compared to the angle at the circumference, and more
• Solve problems related to two and three dimensional symmetry, plane symmetry, circles, and angles
