Title: Exploring the Longest and Shortest Sides of Triangles and Quadrilaterals -A Lesson Plan Introduction: Geometry is afascinating branch of mathematics that deals with shapes, sizes, and their properties. It is an essential subject that helps us understand the world around us. In geometry, we come across various shapes such as triangles, rectangles, squares, and many more. One of the essential characteristics of any of these shapes is their perimeter. The perimeter of ashape is defined as the sum of the lengths of its sides. In this lesson plan, we will explore the longest and shortest sides of triangles and quadrilaterals. Objectives: ● Understand the concept of perimeter and its importance ● Identify and differentiate between the longest and shortest sides of triangles and quadrilaterals ● Explore the relationship between the longest and shortest sides of triangles and quadrilaterals ● Solve problems related to the longest and shortest sides of triangles and quadrilaterals 第1 页共 4页
