Lesson: Special Parallelograms E

There are three special parallelograms Rhombus There are three special parallelograms Rhombus There are three special parallelograms Rectangle Rhombus There are three special parallelograms Rectangle Square Rhombus There are three special parallelograms A rhombus is a parallelogram with congruent sides Rectangle Square Rhombus There are three special parallelograms A rhombus is a parallelogram with congruent sides Rectangle Square Rhombus A rectangle is a parallelogram with congruent angles There are three special parallelograms Rectangle Square Rhombus A rectangle is a parallelogram with congruent angles There are three special parallelograms Rectangle Square A square is a parallelogram with both congruent sides Rhombus There are three special parallelograms and congruent angles Rectangle Square A square is a parallelogram with both congruent sides Rhombus There are three special parallelograms and congruent angles Rectangle Square Rectangle ? Square ? Rhombus ? Square ? Rectangle ? Rhombus ? has congruent sides AND angles has ONLY congruent angles has ONLY congruent sides Each of the special parallelograms also have Each of the special parallelograms also have special properties. Rectangles not only have congruent angles Each of the special parallelograms also have special properties. Rectangles not only have congruent angles Each of the special parallelograms also have special properties. Rectangles not only have congruent angles Each of the special parallelograms also have but the diagonals are also congruent special properties. Rectangles not only have congruent angles Each of the special parallelograms also have but the diagonals are also congruent special properties. Rectangles not only have congruent angles Each of the special parallelograms also have but the diagonals are also congruent special properties. Rectangles not only have congruent angles Each of the special parallelograms also have but the diagonals are also congruent which means all the parts are congruent special properties. Rectangles not only have congruent angles Each of the special parallelograms also have but the diagonals are also congruent which means all the parts are congruent special properties. Rectangles not only have congruent angles Each of the special parallelograms also have but the diagonals are also congruent which means all the parts are congruent special properties. Rectangles not only have congruent angles Each of the special parallelograms also have but the diagonals are also congruent which means all the parts are congruent special properties. Rectangles not only have congruent angles Each of the special parallelograms also have but the diagonals are also congruent which means all the parts are congruent special properties. x y y = x = O O Rectangle n = m = O O m n y = x = 5 Rectangle x z = z y A rhombus has special properties as well A rhombus has special properties as well Not only are the sides all congruent A rhombus has special properties as well Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles and the diagonals are perpendicular Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles and the diagonals are perpendicular Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles and the diagonals are perpendicular 90 Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles and the diagonals are perpendicular 90 90 Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles and the diagonals are perpendicular 90 90 90 Not only are the sides all congruent A rhombus has special properties as well but the diagonals bisect the angles and the diagonals are perpendicular 90 90 90 90 11 y z y = z = x = x rhombus ABCD is a x 60 ^{∘}y z y = z = x = rhombus ABCD is a z x y y = z = x = rhombus ABCD is a A square is BOTH a rhombus A square is BOTH a rhombus AND a rectangle A square is BOTH a rhombus AND a rectangle so ALL the special properties of both A square is BOTH a rhombus AND a rectangle so ALL the special properties of both a rectangle and rhombus A square is BOTH a rhombus AND a rectangle so ALL the special properties of both a rectangle and rhombus apply to a square. |
