In a rhombus, the angle between the diagonal and the side = 25 degrees. Find the corners of the rhombus.

1. It is known:

a) the diagonals of the rhombus divide the corners of the rhombus in half;

b) the opposite angles of the rhombus are equal in pairs;

c) the adjacent corners of the rhombus add up to 180 *.

2. If the angle between the side and the diagonal of the rhombus is 25 *, then this angle of the rhombus is 2 times greater and is equal to

25 * * 2 = 50 *.

The opposite angle is also 50 *.

3. Adjacent with an angle of 50 * together with it give 180 * in total, which means the adjacent angle is

180 * – 50 * = 130 *.

The opposite angle is also 130 *.

Answer: The angles of the rhombus are 50 * and 130 *.
