Sita got a wooden square plate and cut it diagonally, as shown in the figure below. After cutting it, she saw that two triangles are formed.
Can you tell what type of triangles are formed?
If a square is cut diagonally, two sides will be equal (all sides of square are equal).
The third side of triangle formed will not be equal as it is diagonal.
Hence it will be an isosceles right-angled triangle.
