Is it easy to solve the problem with the help of the above diagram? Please use this method to solve the following problem. (first draw a picture) an isosceles right triangle, the length of the hypotenuse is 10cm. What is the area of this triangle?
Use four isosceles right triangles to make a square with side length of 10 cm. The area of the square is 10 × 10 = 100 (cm2). The area of the triangle is 100 △ 4 = 25 (cm2). A: the area of the triangle is 25 square cm
