Area of a Right Triangle - Concept Intro - Half Squares

Level 1

This math topic focuses on calculating the area of right triangles using different unit squares (km², m², in², ft²). It introduces the concept of understanding and representing area through visual interpretation of squares within a triangle. Each problem displays an image of a right triangle superimposed on a grid of squares with varying measurements, and multiple-choice answers are provided for students to select the correct area. The primary skill practiced is visualizing and calculating the area occupied by the right triangle in terms of the given unit squares.
