Answer:
[1] Divisibility Rule of 5: If the last digit is 0 or 5.
Divisibility Rule of 9: Is the sum of the digit is divisible by 9.
[2] According to the associative property of addition, the sum of three or more numbers remains the same regardless of how the numbers are grouped.
The associative property is a math rule that says that the way in which factors are grouped in a multiplication problem does not change the product.
[3] Properties of Parallelogram:
=> The opposite sides are parallel and congruent
=> The opposite angles are congruent
=> The consecutive angles are supplementary
=> If anyone of the angles is a right angle, then all the other angles will be the right angle
=> The two diagonals bisect each other
=> Each diagonal bisects the parallelogram into two congruent triangles
=>Sum of square of all the sides of parallelogram is equal to the sum of square of its diagonals. It is also called parallelogram law
