What is true for a rhombuses angles

Opposite angles are congruent.

Adjacent angles are supplementary (For eg., ∠A + ∠B = 180°).

What is true of the opposite sides of a parallelogram

  • Opposite sides are parallel and congruent.
200

What is true of a squares diagonals

  • The diagonals are congruent.
  • The diagonals are perpendicular to and bisect each other.
200

What is true of the angles in a rectangle

  • Opposite angles formed at the point where diagonals meet are congruent.
200

Diagonals of a Rhombus

  • The diagonals are perpendicular to and bisect each other.
200

What is true of opposite angles of a parallelogram

  • Opposite angles are congruent.
300

How to prove a parallelogram is a square

  • Also, a parallelogram becomes a square when the diagonals are equal and right bisectors of each other.
300

What is true of a rectangles diagonals

  • The diagonals are congruent and bisect each other (divide each other equally).
300

How to prove a parallelogram is a rhombus

  • A rhombus is a parallelogram whose diagonals are perpendicular to each other.
300

The diagonals of a parallelogram do this

  • Diagonals bisect each other and each diagonal divides the parallelogram into two congruent triangles.

Perimeter of a square

Perimeter = 4L

400

The area of a rectangle is

  • Area = L * W
400

Perimeter of a Rhombus

Perimeter = 4L

400

The area of a parallelogram is this equation.

  • Area = L * W
