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
