Hello welcome to MooMooMath. In this video I would like to talk about rectangles,rhombuses,
and squares. Each of these shapes are pland 2 dimensional
shapes. Each of these shapes are considered a polygon,
which is a closed figure composed of line segments.
They also are considered quadrilaterals which mean they each have 4 sides
They also are all parallelograms.which means they have opposite sides that are parallel.
Let's look at some unique properties of a rhombus,rectangle, and a square.
Let's take a look at 14 properties of a rhombus.
A Rhombus is a Quadrilateral, which means it has four sides, and the sides of a rhombus
are congruent. The opposite sides of a rhombus are parallel.
The opposite angles of a Rhombus are congruent. The diagonals of a rhombus are perpendicular.
The diagonals of a Rhombus create form four congruent interior triangles.
The diagonals of a rhombus bisect each other which means they cut each other in half.
The formula for perimeter equals 4 s s equals sides
The formula for area equals 1/2 diameter 1 + diameter 2
a rhombus has all the properties of a parallelogram opposite sides congruent,opposite angles congruent,diagonals
bisect each other All squares are rhombuses but not all rhombuses
are squares
Properties of a rectangle A rectangle is part of the quadrilateral family.
A rectangle is a plane shape with 4 sides. In addition, it has several other properties
A rectangle is a 4 sided polygon, with opposite sides being parallel.
In addition, a rectangle has 4 right angles and the sum of the interior angles add to
360 degrees. The diagonals of a rectangle are equal length
The diagonals bisect and create two equal triangles.
Opposite sides are equal and parallel All squares are rectangles, but not all rectangles
are squares. Properties of a square
A square is a plane shape that is a quadrilateral that is 2D so it has length and width but
not height. A square has 4 congruent sides 4 equal sides.
Along with these 4 sides a square has 4 right angles
The diagonals are perpendicular and create 4 right angles.
The diagonals bisect each other. The diagonals of a square also bisect opposite
angles and create equal 45 degree angles.
The diagonals create congruent triangles Triangle ABC is congruent to ACD
A square can be considered a rhombus with four
right angles or a square with 4 equal sides. Thanks for watching
