Area of a Non-Right Triangle - Concept Intro - From Rectangle (Level 2)

This math topic focuses on practicing how to find the area of non-right triangles by visualizing and halving the area of a rectangle surrounding the triangles. The topic is at a Level 2 difficulty and serves as an introduction to understanding triangle areas. Throughout multiple questions, students are provided with images representing triangles within rectangles and are required to calculate the triangle's area by utilizing the rectangle's area. This method helps consolidate the student's understanding of spatial properties and the relationship between different geometric shapes.
