Names Of Triangle

-Equilateral.

-Isosceles

-Right-angled

-Scalene

-Obtuse

-Acute

Right-Angled Triangle- A right triangle or right-angled triangle, or more formally an orthogonal triangle, is a triangle in which one angle is a right angle.

Obtuse- An obtuse angle is an angle that measures more than 90 degrees and less than 180 degrees

Acute-The acute angle is the small angle which is less than 90˚. It is one of a number of basic types of angles, along with a right angle.

Scalene-A scalene triangle is a triangle in which all three sides have different lengths. Also, the angles of a scalene triangle have different measures

Isosceles- An isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length,

Equilateral- An equilateral triangle is a triangle in which all three sides have the same length

3 facts about triangles: 

• The sum of all the internal angles of a triangle is always 180o no matter how the triangle is constructed.

• The length of any side of a triangle is shorter than the sum of the other two sides.

• A triangle can always be split into two right triangles no matter how the triangle is constructed.

Pythagoras Therum:

Who is Pythagoras: Pythagoras was a Greek philosopher and mathematician. When he was about 20 years old he visited the philosophers Thales and Anaximander on the island of Miletus.

When was Pythagoras invented: Pythagoras of Samos was born circa 569 BC in Samos, he was the first mathematician. 

What was his role: His political and religious teachings were well known in Magna Graecia and influenced the philosophies of Plato, Aristotle, and, through them, Western philosophy.

Where did he live: He lived in Metapontum Village, Croton

How does The Therum of Pythagoras work: Pythagoras theorem states that for all right-angled triangles, 'The square on the hypotenuse is equal to the sum of the squares on the other two sides. The hypotenuse is the longest side and it's always opposite the right angle.

What is a Square and what is Square Root?

Square- A square number is a result when a number has been multiplied by itself. For example, 25 is a square number because it's 5 x 5. This is written in 52

Square Root- A number that produces a specified quantity when multiplied by itself.

What is a prime number in the square? - All square numbers have an odd number of factors. A prime number by definition has exactly 2 factors.
