2. Consecutive angles of a rhombus are ___________________.
3. Opposite angles of a rhombus are ___________________.
Next, you will look at the properties of the angles created by the diagonals of a rhombus. Open the file READ2. You are given rhombus READ and the measure of angles
4. Move point
Open the file READ3. You are given rhombus READ and the measure of all angles created by the diagonals of the rhombus.
