r: The distance from the center of a circle to any point on the circle is called the radius.

d: The distance across and through the center of a circle is called the diameter.

The diameter is always equal to twice the radius.

If the radius is 3, the diameter is 2 × 3, or 6.

The circumference of a circle is the distance all the way around the outside edge of the circle. In other words, circumference is the name for a circle's perimeter.

A long time ago an Egyptian mind took a rope and cut it equal to the distance through the trunk of a tree. He cut another rope equal to the distance around the trunk of the tree. The rope that equaled the distance around the trunk was three times as long! But wait! Not exactly! It was a little over three times. This magic number is called pi or π. It has the approximate value of 3.14.

PYTHAGOREAN THEOREM

Right angle triangle

Pythagorean theorem
Mi5Pa9 PiTRaGoX משפט פיתרגוס 

Hypotenuse
YeTeR יתר



The three angles inside a triangle always add up to 180°, no matter how the triangle is drawn.

PYTHAGOREAN THEOREM 

-A right angle triangle contains one angle that equals 90°.

the sides of a right triangle are always in a particular proportion which can be expressed by the formula A^2 + B^2 = C^2, in which A and B are the two shorter sides of the triangle, and C is the longer side opposite the 90-degree angle. This longer side is called the hypotenuse.

3-4-5 triangle

TESTING THE THEOREM

3^2 + 4^2 should equal 5^2. Does it? Yes! 9 + 16 does equal 25.

GEOMETRY

Geometry

perimeter
HeQeF הקף



Area of a rectangle=L × W
Volume of a rectangle=L × W × D
Area of a square=side^2
Volume of a cube=side^3
Perimeter of a rectangle=add all sides
Area of a triangle=base × height ÷ 2

A pyramid is a three-dimensional shape made of four sides that suit atop a rectangular base.

Volume of a pyramid=bh ÷ 3

Finding the volume of a pyramid is just like finding the volume of a rectangle or cube except you divide by three. Why do you divide by three? Because a pyramid is a cube with three as it's strength instead of 4.

SQUARE ROOTS

MATH


Square root
5oRe5 MRuBa7 שורש מרובע

RADICALS
The square root of a positive number x is the number that, when squared, equals x.

For example:

The square root of 16 equals 4 because 4 × 4 = 16.
The square root of 9 equals 3 because 3 × 3 = 9.
The square root of 4 equals 2 because 2 × 2 = 4.

The symbol for a positive square root is √, also called a radical.

√16=4
√9=3
