Given that ABCD is a parallelogram, tell which kind of special parallelogram is identified in the following:
1. AC=BD
2. AC = 4 cm, BD = 6 cm
3.m/A=m/B = m/C = m/D
4. AABD and ABCD are isosceles right triangles.
5. m/ABD = m/CBD, m/ADB = m/CDB
6. AC = BD, AB = BC, CD = DA
1. AC=BD
2. AC = 4 cm, BD = 6 cm
3.m/A=m/B = m/C = m/D
4. AABD and ABCD are isosceles right triangles.
5. m/ABD = m/CBD, m/ADB = m/CDB
6. AC = BD, AB = BC, CD = DA

Answer:
1. In the given condition, where AC = BD, we can identify that the parallelogram ABCD is a rectangle. In a rectangle, opposite sides are equal in length and all angles are right angles.
2. In this case, where AC = 4 cm and BD = 6 cm, we cannot identify a specific kind of parallelogram. The given information only tells us about the lengths of the diagonals, but it doesn't provide enough information to determine any other specific properties of the parallelogram.
3. When the measures of angles A, B, C, and D are equal (m/A = m/B = m/C = m/D), the special parallelogram identified is a rhombus. A rhombus has all sides equal in length and opposite angles equal in measure.
4. If both AABD and ABCD are isosceles right triangles, then the parallelogram ABCD is a square. A square is a special type of rectangle where all sides are equal in length and all angles are right angles.
5. When the measures of angles ABD and CBD are equal (m/ABD = m/CBD) and the measures of angles ADB and CDB are equal (m/ADB = m/CDB), we can identify that the parallelogram ABCD is a kite. A kite has adjacent angles that are equal, but its sides are not necessarily equal in length.
6. In this case, where AC = BD, AB = BC, and CD = DA, the special parallelogram identified is a square. A square has all sides equal in length and all angles equal to 90 degrees, making it a type of rectangle.
