What quadrilateral has perpendicular bisectors?
What quadrilateral has perpendicular bisectors?
Rhombus
Proof: Rhombus diagonals are perpendicular bisectors.
How do you find the diagonal of a quadrilateral?
If we suppose the length of a square is L, then the length of the diagonal = L √2. Area of a square = L2. A quadrilateral whose four sides are all congruent in length is a rhombus.
How many diagonals does a quadrilateral have?
2 diagonals
Hence a convex quadrilateral has 2 diagonals.
What is another name for an equiangular quadrilateral?
An equiangular quadrilateral, i.e. the one with all angles equal is a rectangle. All angles of a rectangle equal 90°. An equilateral quadrilateral, i.e. the one with all sides equal, is a rhombus. In a square, rectangle, or rhombus, the opposite side lines are parallel.
What are some of the properties of special quadrilateral?
Properties of Special Quadrilaterals
- The opposite sides are congruent.
- The opposite sides are parallel.
- The opposite angles are congruent.
- The consecutive angles are supplementary.
- The diagonals bisect each other.
How do you find the diagonal of an irregular quadrilateral?
