Equilateral is when all sides in that shape are the same length
Tri is a shape with 3 sides
Quad is a shape with 4 sides
Pent is a shape with 5 sides
Hex is a shape with 6 sides
Square
Four equal sides, angles all 90*
In geometry, a square is a regular quadrilateral, which means that it has four equal sides and four equal angles (90-degree angles, or (100-gradian angles or right angles). It can also be defined as a rectangle in which two adjacent sides have equal length.
Rectangle
A rectangle is cyclic: all corners lie on a single circle.
It is equiangular: all its corner angles are equal (each of 90 degrees).
It is isogonal or vertex-transitive: all corners lie within the same symmetry orbit.
It has two lines of reflectional symmetry and rotational symmetry of order 2 (through 180°).
Rhombus
A Rhombus is a flat shape with 4 equal straight sides. A rhombus looks like a diamond. All sides have equal length. Opposite sides are parallel, and opposite angles are equal (it is a Parallelogram). The altitude is the distance at right angles to two sides.
Parallelogram
A parallelogram is a quadrilateral with opposite sides parallel (and therefore opposite angles equal). A quadrilateral with equal sides is called a rhombus, and a parallelogram whose angles are all right angles is called a rectangle.
Is there any other four sided shapes you know?
hey mate i am really impressed with your work.one four sided shape i know is a trapezoid. really good work mate top marks.
ReplyDeleteHey mate Jayden here cheers for the 9 :)
Deleteyou've done a good job with your work Jayden. I know that kite is another shape that has four sides
ReplyDeletenice job bud this is really giving me a good understanding of these shapes.
ReplyDeleteI like the information in this maybe you could have explained what quadrilateral was.
ReplyDeleteHi Jayden! You did a great job! I like how you explain each of them clearly. I think you forgot to put a picture of parallelogram. Just that, everything is Great!
