In today’s lesson, we explored the parts of a circle, including important terms used in circles such as circumference, diameter, radius, and chord. The circumference is the distance around the circle, while the diameter is the line segment that passes through the center and connects two points on the circle. The radius is half of the diameter, extending from the center to the circumference. We also discussed how to visualize these concepts using a compass to draw a complete circle and measure the necessary dimensions.
