What are the side lengths of a 30 60 90 Triangle?

What are the side lengths of a 30 60 90 Triangle?

What is a 30-60-90 Triangle? A 30-60-90 triangle is a special right triangle whose angles are 30º, 60º, and 90º. The triangle is special because its side lengths are always in the ratio of 1: √3:2.

How do you find two unknown sides of a right triangle?

Right Triangles and the Pythagorean Theorem

1. The Pythagorean Theorem, a2+b2=c2, a 2 + b 2 = c 2 , can be used to find the length of any side of a right triangle.
2. The side opposite the right angle is called the hypotenuse (side c in the figure).

What is a non right triangle?

Any triangle that is not a right triangle is an oblique triangle. Solving an oblique triangle means finding the measurements of all three angles and all three sides. SSA (side-side-angle) We know the measurements of two sides and an angle that is not between the known sides.

Are trigonometric functions only for right triangles?

For Trigonometric functions to work you need a hypotenuse, which you can only get in right triangles. When you are dealing with triangles other than right triangles, the solution is to draw a perpendicular line to create right triangles.

Is hypotenuse only for right triangles?

Yes, the hypotenuse is always the longest side, but only for right angled triangles. For isosceles triangles, the two equal sides are known as the legs, while in an equilateral triangle all sides are known simply as sides.

Is the hypotenuse the longest side?

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles. The hypotenuse of a right triangle is always the side opposite the right angle.

What is the shortest side in a right triangle?

In any triangle, the longest side is opposite the largest angle, and the shortest side is opposite the smallest angle. Thus, in a right triangle, the hypotenuse is always the longest side.

Is C the hypotenuse?

In any right-angled triangle, ABC, the side opposite the right-angle is called the hypotenuse. The side opposite B is labelled b and the side opposite C is labelled c. Pythagoras’ theorem states that the square of the hypotenuse, (c2), is equal to the sum of the squares of the other two sides, (a2 + b2).
