The longest side of the right angles triangle is called the hypotenuse. Divide the length of the side opposite the chosen angle by the length of the hypotenuse. This is the Sine of the angle.

What kind of triangle that has 2 acute and 1 right angle?
That would be a right triangle. Any triangle that has a right angle in it is a right triangle.
How do you find the angle of a right triangle with the length of two legs?
-- Like every triangle, a right triangle has three interior angles.-- Unlike any other triangle, one of the angles in a right triangle is a right angle.The other two are both acute angles.-- One acute angle is the angle whose cosine is length of one leg / length of hypotenuse-- Other acute angle is the angle whose sine is length of the same leg / length of the hypotenuse-- The length of the hypotenuse is the square root of [ (length of one leg)2 + length of other leg)2 ]
A right angle triangle is how many degrees?
The sum of all angles in any triangle is 180o The largest angle in aright angle triangle is 90o
Shapes that have one right angle?
Any polygon can have just one right angle, from a right angled triangle upwards.
How do you find the missing length of a triangle?
You use the Pythagoras Theorem if it is a right-angled triangle. a squared + b squared = h (longest side, diagonal) squared, then square root h to find the longest side. if it is not a right angled triangle, then use the Sine or Cosine rule. Sine rule for: two angles and any one side or two sides and an angle that is not in between the sides. Cosine rule for: all three sides (but then you do not need to find a missing side) or two sides and an angle that is in between.
How do you solve sohcahtoa?
It means for any right angle triangle:- sine = opposte/hypotenuse cosine = adjacent/hypotenuse tangent = opposite/adjacent

What is the equation for finding sinฮธ and what is this usually going to tell us?
For a right angle triangle sine or sin angle = opposite/hypotenuse y = sinθ, for any angle θ, -1 ≤ sinθ ≤ 1.
Does an isosceles triangle have a right angle?
An isosceles triangle has two equal sides and two equal angles. A right triangle is any triangle with one angle that is a right angle. A right triangle could also be an isosceles triangle, but an isosceles triangle will not always have a right angle.
What does sine theta mean?
Theta is just a Greek letter used to denote measurement of angle. Sine is a trigonometric function, i.e., the ratio of the side opposite to the angle theta to the hypotenuse of the triangle. So Sine theta means the value of sine function for angle theta, where theta is any angle.
What do you call A triangle with a 90 degrees angle?
Any triangle with a 90 degree angle is called a right triangle.
What do you do in trigonometry?
usually its used to find a missing angle or length of a right triangle. Of course there is more to trigonometry. any way you can use sine, cosine, and tangent, to fine the missing angle or length
Can any triangle be a right triangle?
no a right triangle HAS to have an angle that measures 90 degrees.
Can the sine law be usd in a right triangle?
Yes, the law of sines can be used in a right triangle. The law applies to any arbitrary triangle.
Prolem and solution of right triangle?
Pythagorean Theorum. A2+B2=C2 That is the topic of study in trigonometry. Trig gets into the trig functions (sine, cosine, tangent...) and since the subject is quite involved, it can't be adequately explained in this type of setting. However... Imagine a right angle triangle, any right angle triangle (that means a triangle in which one side has 90 degrees but you don't necessarily know any other angle of the triangle. If you want to know a specific angle of the triangle (other than the right angle), you COULD measure two lengths of the triangle and calculate the angle using trig functions. The hypotenuse is the segment of the triangle that is opposite the right angle. To calculate the angle in question, measure the OPPOSITE segment (that means the segment that is furthest from the angle), then measure the hypotenuse (explained above). At that point you divide the length of the opposite segment by the length of the hypotenuse and look up the results in your handy sine table (or use your calculator if it has trig functions) and it will give you the angle. Phew! That was a long explanation, and to go into trig functions any further would require a classroom, but basically that's how you would solve a right triangle question.
Can trigonometry be used with right triangles only?
No, trigonometry can be used with any triangle, right angle or not. While the primary trigonometric functions are defined in relation to right triangles with hypoteneuse equal to 1, that is just a special case where the function is easier to define. Sine (theta), for instance, is opposite over hypotenuse, where the angle on the other end of adjacent is a right angle. Even if you don't have a right angle, the functions can help you find a superposition of a right triangle on any triangle, and that can help you solve many different kinds of problems. The laws of sines and cosines, for instance, apply to any triangle.
What triangles can be classified as a right triangle?
Any triangle that has a 90 degree angle and two acute angles is a right angle triangle.
