The diagonal divides the corner of the rectangle in a ratio of 1: 2 and the smaller side is 12cm. Find the diagonal of the rectangle.

1) The angle of the rectangle is 90º. If the diagonal of the rectangle divides the angle by a ratio of 1: 2, then 30º and 60º angles will be formed.

2) A rectangle divided by a diagonal is made up of two right-angled triangles, where the diagonal is the hypotenuse.

3) In a right-angled triangle, the smaller side (leg, 12 cm) will lie opposite a 30 ° angle.

4) The leg of a right-angled triangle is equal to half of the hypotenuse if it lies opposite an angle of 30 degrees, and the diagonal of the rectangle is: 12 * 2 = 24 cm.
