If the length of the opposite side of a 45 degree angle in a right triangle is 1, then the length of the adjacent side is - and the length of the hypotenuse is -, so sin 45 = -, cos 45 = -

If the length of the opposite side of a 45 degree angle in a right triangle is 1, then the length of the adjacent side is - and the length of the hypotenuse is -, so sin 45 = -, cos 45 = -

From the beginning to the end, the answer is 1 root 2
Root 2 / 2 root 2 / 2

The area of isosceles right triangle with 8 cm hypotenuse is equal to______ cm2．

The hypotenuse of an isosceles right triangle is 8cm, the height of the hypotenuse is 12 × 8 = 4cm, and the area of the triangle is 12 × 8 × 4 = 16cm2
