That is a RIGHT triangle. You have to know the length of one of the sides to determine the length of the other two. The formula used is A squared plus B squared equals C squared. Imagine a triangle with a vertical line 3 inches long. Call that vertical line "A". Starting at the base of the vertical leg draw a horizontal line to the right that is 4 inches long. Call that horizontal line "B". Now connect the top of "A" to the right end of "B" with a diagonal line. Call that line "C". That diagonal line is 5 inches long. We know this because 3 squared (A) is 9 and 4 squared (B) is 16 and 9+16=25, the square root of which is 5.

How can you find the measures of the sides of a triangle?
There are many theories and formulas that can be applied to find the length of each of the sides of a triangle. The most common is the Pythagorean Theorem: a2+b2= c2 . The letters: "a , c" are the two legs. The hypotenuse is the letter "c". For a 30-60-90 triangle you can use a special formula, as well as a 45-45-90 triangle.
Is a triangle with sides of lengths 16 30 and 35 a right triangle?
No because it does not comply with Pythagoras' theorem.
How do you find the sides of a 30 60 and 90 degree triangle?
you cannot determine the sides of a triangle by the angle measures alone because any triangle with different side lengths can have these angle measurements. However if you do know the length of any one of the sides, you can calculate the lengths of the other two sides.The shortest side is the one opposite the 30 degree angle.The hypotenuse (opposite the 90 degree angle) is always twice the length of the shortest side opposite the 30 degree angle.The side opposite the 60 degree angle is always the length of the side opposite the 30 degree angle times the square root of three (about 1.73205).
How many sides a polygon have with an angle 30?
Smallest possible interior angle of regular polygon is 60 degrees (triangle). The greater the number of sides, the greater each interior angle. If exterior angle is 30 degrees, the polygon has 12 sides.
Is a triangle with sides of lengths 20 21 and 30 a right triangle?
No.(20)2 = 400(21)2 = 441(20)2 + (21)2 = 881(30)2 = 900(20)2 + (21)2 is not equal to (30)2
How can you determine whether a triangle is a right triangle if you only have the lengths of its three sides?
The pathagoren theorm states that a2+ b2 = c2. If you put your lenghts into the equation and it comes out true (100=100), then the triangle is a right trianlge. If it is a false equation (100=30), then it is not a right triangle. Where a = lenght of leg 1, b = lenght of leg 2, and c = lenght of hypotenuse.
Are a triangle with sides 12 in and 8 in and a triangle with sides 24 in and 30 in similar?
No, because 8 isn't a factor of 30.
Definition of the 30-60-right triangle theorem?

Can you give me the name of triangle that is two of three angles are 30 and 60?
A right triangle. All the angles of a triangle add up to 180. 30+60+x=180. subtract 30 from both sides, then 60 from both sides and x=90
What is a triangle that has two angles that are 30 each and two shorter sides that is the same?
isosceles triangle
How can you find the measures of the sides of a triangle?
There are many theories and formulas that can be applied to find the length of each of the sides of a triangle. The most common is the Pythagorean Theorem: a2+b2= c2 . The letters: "a , c" are the two legs. The hypotenuse is the letter "c". For a 30-60-90 triangle you can use a special formula, as well as a 45-45-90 triangle.
How do you know if it is a 30-60-90 triangle?
If the ratio of the three sides are 1:√(3):2, it's a 30-60-90 triangle
Is a triangle with sides of lengths 16 30 and 35 a right triangle?
No because it does not comply with Pythagoras' theorem.
Perimeter of a right angled triangle is 30 cm and its hypotenuse is 13 cm. Find the other two sides?
Let the two sides of the right-angled triangle be a and b. Given that the perimeter is 30 cm, we have a + b + 13 = 30. Since the triangle is right-angled, we can use the Pythagorean theorem: a^2 + b^2 = 13^2. We now have a system of two equations that can be solved simultaneously to find the values of a and b.
What is the area of a triangle whose sides measure 30 meters 70 meters and 40 meters?
Zero. The two shorter sides together make 70 metres, so they lie flat against the longest side. Really, there is no triangle. If the 3 sides actually make a triangle, you can use Heron's formula - look it up - to find the area.
Can 16 30 and 34 be a triangle leangth?
No. But they can be the lengths (not leangths!) of the three sides.
What is the name of a triangle with 30 perimeter?
The fact that it has a 30 perimeter tells you nothing about the triangle's angles and very little about the lengths of its sides. The name, if it has any, is indeterminate.
