In today’s lesson, we focused on forming equations from geometric shapes, particularly rectangles and triangles. We began by discussing how to calculate the perimeter and area of these shapes, utilizing properties such as the angles in a rectangle and triangle. Through examples, we established that the perimeter of a rectangle involves adding all its sides, while also simplifying expressions to find the perimeter for both shapes. Students were guided on how to rearrange and solve equations to derive the desired dimensions effectively.
