A) Which of the following are properties of all rhombus? Check ALL that apply (3 points)
The diagonals bisect each other at a 90 degree angle
All four sides are equal length
The diagonals are congruent
All angles are 90 degrees
Opposite angles are equal

1 answer

The properties of all rhombuses include the following:

  1. The diagonals bisect each other at a 90-degree angle - True
  2. All four sides are equal length - True
  3. The diagonals are congruent - False (The diagonals in a rhombus are not necessarily congruent; they are orthogonal and bisect each other but can be of different lengths.)
  4. All angles are 90 degrees - False (A rhombus does not have to have all angles as 90 degrees; however, if it does, it is a square.)
  5. Opposite angles are equal - True

So, the correct properties of all rhombuses are:

  • The diagonals bisect each other at a 90-degree angle
  • All four sides are equal length
  • Opposite angles are equal
