Answer/Step-by-step explanation:
We are told that:
Area of the given square = 1 square units
2 of the small triangles will make up the square when joined together.
Since area of the square is 1 square units, area of the 2 small triangles = 1 square units.
We are also told that 2 of the small triangle will also make up the medium triangle when joined together.
Therefore, since area of 2 small triangles = area of the square = 1 square units, the medium triangle would also have an area of 1 square units.
1. Area of the small triangle is ½ square units. I know this because 2 small triangles = area of the square = 1 square units.
2. The area of the medium triangle is 1 square units. I know this because 2 small triangles make up the medium triangle, and 1 small triangle has an area of ½ square units.
3. The area of the large triangle is 2 square units. I know this because if the medium triangle is made up of 2 small triangles, then 4 small triangles will make up the big triangle, or 2 medium triangle will make up the big triangle.
