Is Sin Cos Tan only for right triangles?

Is Sin Cos Tan only for right triangles?

The Sine Rule can be used in any triangle (not just right-angled triangles) where a side and its opposite angle are known. You will only ever need two parts of the Sine Rule formula, not all three. You will need to know at least one pair of a side with its opposite angle to use the Sine Rule.

Are of a right angle triangle?

A right triangle consists of two legs and a hypotenuse. The two legs meet at a 90° angle and the hypotenuse is the longest side of the right triangle and is the side opposite the right angle. There are a couple of special types of right triangles, like the 45°-45° right triangles and the 30°-60° right triangle.

How do you name a right triangle?

is a right triangle. The sides of a right triangle have different names: The longest side, opposite the right angle, is called the hypotenuse. In the diagram, the hypotenuse is labelled c. The other two sides are called the legs of the triangle.

Can a right angled triangle be equilateral?

An equilateral triangle can not be a right triangle. In a right triangle, however, the 3 angles can NOT be congruent. This is because in a right triangle, one angle equals 90 degrees. Therefore, you can't have 3 angles equal 90 degrees.

Where is trigonometry used?

Apart from astronomy and geography, trigonometry is applicable in various fields like satellite navigation, developing computer music, chemistry number theory, medical imaging, electronics, electrical engineering, civil engineering, architecture, mechanical engineering, oceanography, seismology, phonetics, image

Does trigonometry apply to all triangles?

No, they work for all triangles. The word, trigonometry, itself stems from Greek, and it means measuring triangles. There are rules that only pertain to right triangles, but they are really just the special case where one angle is 90 degr. A limited, if important, use.
