A 30-60-90 triangle is a triangle whose angles of 30º, 60º, and 90º. The lengths of the sides of a 30-60-90 triangle are always in a fixed ratio. Suppose the short leg, opposite the 30º angle, has length x. Then the hypotenuse has length 2x, and the long leg, opposite the 60º degree angle, has length (sqrt 3)x. The sides of every 30-60-90 triangle will have this 1 : 2 : sqrt(3) ratio. (sqrt (3) means the square root of 3)

What are the differences of isosceles right triangles and 30-60-90 right triangles?
isosceles are 45-45-90
How do you solve the HCF of 60 and 90?
It is 30 because it's the highest common factor of 60 and 90
If you split a rectangle into 2 triangles what type of triangle do you get?
A 30-60-90 right triangle
What triangles are classified by their angles?
Acute triangles have all of their angles less than 90 degrees. Right triangles have one of their angles equal to 90 degrees. Obtuse triangles have one of their angles greater than 90 degrees. Also, the 45-45-90 triangle and 30-60-90 triangle are useful when trying to get exact answers in trigonometry.
What kind of triangle has one 30 degree angle and one 60 degree angle?
A right triangle because all triangles equal 180 degrees. 180-60=120 120-30=90
Are all 30-60-90 triangles isosceles?
No because 30-60-90 triangles are right angle triangles
What are the differences of isosceles right triangles and 30-60-90 right triangles?
isosceles are 45-45-90
Special right triangles?
30-60-90 45-45-90
What are some types of triangles by degrees?
special triangles: 45-45-90 triangle and 30-60-90 triangle
What is the answer to the ratio 60 to 90?
To solve this, set up the problem as a fraction: 60/90. Then reduce. The GCF of 60 and 90 is 30. Divide 30 into both 60 and 90 and you get a ratio of 2 to 3.
How do you solve the HCF of 60 and 90?
It is 30 because it's the highest common factor of 60 and 90
How do you do special triangles 90 60 30?
That depends on what you want to 'do' to them. It helps to remember these two simple facts. They will solve most of the problems that involve a 30-60-90 triangle: -- The side opposite the 30 is (1/2 of the hypotenuse). -- The side opposite the 60 is (1/2 of the hypotenuse) times the sqrt(3) (or 31/2).
What is a 30 60 90 triangle?
A 30, 60, 90 triangle is a right triangle. It's one of the most common triangles to use to learn about the Pythagorean theorem.
If you split a rectangle into 2 triangles what type of triangle do you get?
A 30-60-90 right triangle
A 30 o-60 o-right triangle is half of what other kind of triangle?
90
What is the 30-60 right angle?
It is a triangle that has these 3 angles at its corners: 30, 60 and 90 degrees. This is one of the more common triangles as many designs are laid out at 30 degrees or 60 degrees.
Do different 30 60 90 triangles have same perimeter and area?
No, they have the same angles but may vary in size.
