1. It is known that the length of the hypotenuse of an isosceles right triangle is 10cm, and the waist length of the isosceles triangle is calculated 2. There are four identical right triangles to form a large square. As shown in the figure, it is known that the lengths of the two right sides of a right triangle are 6cm and 8cm respectively. To find the area of a large square, the Pythagorean theorem is used in both problems

1) Let the waist length be x, then x ^ 2 + x ^ 2 = 10 ^ 2
2x^2=100
x^2=50
x=5√2（cm）
Where is the second picture?

Make a set of Tangram with 16 cm square, as shown in the figure below

Square area: 16 × 16 = 256 (square centimeter) area: 256 × 14 = 64 (square centimeter) area: 256 × 116 = 16 (square centimeter) area: 256 × 18 = 32 (square centimeter) area: ① area is 64 square centimeter, ③ area is 16 square centimeter, and ② area is 32 square centimeter
