Area of a Right Triangle - Concept Intro - From Rectangle

Level 3

This math topic focuses on calculating the area of right triangles by using the area formula of rectangles. Students are expected to find the area of a triangle by first calculating the area of a surrounding rectangle and then dividing that area in half. Each problem presents a right triangle within a rectangle, and students must apply the concept that the triangle's area is half of the rectangle's area. This method provides an introductory understanding of geometry principles, particularly focusing on how the dimensions of rectangular shapes relate to right triangles enclosed within.
