@rz923 This shape is called a sector in maths. A sector is a plane figure that is enclosed by two radii of a circle or ellipse and the arc between them, such as the one Prof. Loh draw. A wedge is a tool that tapers to a thin edge. They have different meanings, but Prof. Loh just used the word "wedge" to make it easier to visualize and understand.
@iamnotawhale Yeah, that's a really good solution too! Just goes to show how there are so many different ways to solve something, all equally unique and efficient 🙂
