**Smart math**to Practice - Easy

**Mathematics**Key to success

Use

**mathematical**key, to facilitate you master the basic math so you will get the title of best in class.

**Key math**is a basic method that must be mastered by the student, the next step is often to practice using the mathematical key continuously will eventually memorized by itself.

In the order shown above has the properties: such as rectangular, square, triangle, trapezoid, parallelogram, kite, and circles. Build Flat names are as follows: Rectangle have which has a flat up against the side of the same length, and has four points right angle.

Square have the sides are all the same length.

Parallelogram have rectangle whose sides are in pairs equal in length and parallel.

Trapezium have which is a rectangle that has a proper pair of parallel sides.

Triangle have which is formed by a flat up three points that are not in line among others: equilateral triangle, isosceles triangle, right triangle, any triangle

*Rotational symmetry and rotational symmetry*

Isosceles triangle has one symmetry Rotational, the rotational symmetry.

equilateral triangles have three-fold symmetry, three rotational symmetry.

Square has four-fold symmetry, four rotational symmetry.

Rectangle has two fold symmetry, two rotational symmetry.

Parallelogram not have Rotational symmetry, has two rotational symmetry.

Isosceles triangle has one symmetry Rotational, the rotational symmetry.

equilateral triangles have three-fold symmetry, three rotational symmetry.

Square has four-fold symmetry, four rotational symmetry.

Rectangle has two fold symmetry, two rotational symmetry.

Parallelogram not have Rotational symmetry, has two rotational symmetry.

*Rhombus has 2 Rotational symmetry, two rotational symmetry.*

*Folding symmetry circle of infinity, infinite rotational symmetry.*

*Ellipse has two Rotational symmetry, two rotational symmetry.*

*Questions and how to resolve by Use*

**Smart mathematical**keyRectangle has a length of 24.5 cm, 13.5 cm breadth. What is the perimeter of the rectangle?

P = 2 X ( l + B )

= 2 X ( 24,5 + 13,5 )

= 2 X 38 = 76 cm

Mr. Bam has a rectangular plot of land with an area of 300 ha. Land length equal to three times the width. What is the land size image Mr.Bam a scale of 1: 100,000

Area = 300 ha = 300,000 cm ²

length = 3 x width

length: width = 3 : 1

length = 3000 m = 300,000 cm

Width = 1000 m = 100.000 m

length in the picture = 300,000: 100,000 = 3 cm

Width of the image = 100,000: 100,000 = 1 cm

Probably not smart if a student without knowing how to use the formula of a key or understand mathematical rules that must be followed by guide or basic mathematics itself. be required for students to learn by using a mathematical formula formula one example that I gave "
