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).

What is 30-60-90 right triangle?

A 30-60-90 right triangle is one in which the three angles of the triangle 30, 60 and 90 degrees. The length of the sides of such a triangle have the ratio 1:2:square root of 3. The 1 is opposite the 30 degree angle, the 2 is opposite the 60 degree angle and the square root of 3 is opposite the 90 degree angle.


How do you find the length of the sides if the right triangle has 60 degrees?

Since the triangle is a right triangle, then it has a 90 degree angle. Given the fact that another of the angles is 60 degrees, the third angle MUST be 30 degrees. This is because the three angles in a triangle must add up to 180 degrees total. So you are talking about one of the "special" triangles... a 30-60-90 triangle. In a 30-60-90 triangle, the ratios of the lengths never changes, and here is how your figure them out. Find the 30 degree angle. The leg opposite that angle should be of length 1. Find the 60 degree angle. The leg opposite that angle should be sqrt(3). Find the hypotenuse. Its length should be 2. So for a 30-60-90 triangle, the lengths are 1-sqrt(3)-2 OR any multiple of this.


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.


What is a triangle with to 30 degree angles and one 120 degree angle?

It is an isosceles triangle.


The lentgh of the hypotenuse of a 30 -60 degree right triangle is 7.5 meters find the length of the opposite side of the 30 degree angle?

It is: 7.5*sin(30) = 3.75 meters


How do you find missing sides of a 30-60-90 triangle?

for a 90 you have to use Pythagoras rule a2+b2=c2 c been the longest side usually in front of the right angle side. For a 30 you have to use this formula 1/2absinc. ab are the two sides you know and c is the angle 30. The same thing works for 60 degree triangle also. hope i helped.


How do you find the area of a 30 60 90 degree triangle?

1/2 length multiplied by height.


A triangle that has 1 90 degree angleand 2 45 degree angle?

okay, what about it? two of its sides are identical. the third side will be rad 2 times as long as the two identical sides. this is a kind of special triangle, another being an eqilateral (60/60/60) and 30-60-90.

How do you find the area of a 30-60-90 degree triangle that has a square root as a side length?

Same as you would find the area of any triangle A = (1/2)[base][height]


How do you find length of a hypotenuse of a 30 60 90 degree triangle is 7 cm what is the perimeter?

The length of the other two sides is 7 cosine (60) and 7 cosine (30)that is 3.5 and 6.062 cmthe perimeter = 7 + 3.5 + 6.062 = 16.562 cm


What is the thirty degree sixty and degree right triangle theorem?

If the triangle has a 30 degree angle and a 60 degree angle then the 3rd angle must be a 90 degree angle because there are 180 degrees in a triangle and so therefore it is a right angle triangle.
