Area of a Right Triangle - On Grid - Image to Area (Level 2)

Topic 103

This math topic focuses on calculating the area of right triangles using a grid. Students are presented with images of right triangles placed on a grid of 1x1 squares and must determine the area using the formula for the area of triangles (half the base times the height). Each exercise includes multiple-choice answers, encouraging practice in visualizing and calculating the areas effectively. This is part of an introductory unit on triangle area calculations, aimed at enhancing students' understanding of geometric concepts and spatial visualization skills.
