How do you solve sohcahtoa?
It means for any right angle triangle:- sine = opposte/hypotenuse cosine = adjacent/hypotenuse tangent = opposite/adjacent
How do you use sine in math?
The sine function is used in trigonometric calculations when attempting to find missing side lengths of a right triangle. The sine of an angle in a triangle is equal to the length of the side opposite of that angle divided by the length of the hypotenuse of the triangle. Using this fact you can calculate the length of the hypotenuse if you know an angle measure and the length of one leg of the triangle. You can also calculate the length of a leg of the triangle if you know an angle measure and the length of the hypotenuse.
How long must a right triangle be?
It can be any length; a right angle triangle just needs to include a right angle somewhere. But length has nothing to do with whether it is a right angle or not.
What is the formula to find the length of a right angle triangle?
By using Pythagoras' theorem for a right angle triangle.
What is right angle triangle and isoceles triangle?
A right angle triangle is a triangle with an angle 90 degrees. An isosceles triangle is a triangle with two or more equal angles/ length of lines. An equilateral triangle can also be an isosceles triangle.

Is it true the sine ratio relates the length of the leg the angle that is in question to the length of the hypotenuse?
Yes... opposite an angle of a right triangle to the length of the triangle's hypotenuse.

What ratio relates the length of the leg opposite the angle in question to the length of the leg adjacent to the angle?
This ratio is the tangent of the angle.If the triangle is a right angled triangle and the angle in question is not the right angle, then it is the tangent of the angle in question.
What does right isosceles mean?
An isosceles triangle is a triangle that has two sides of equal length. A right triangle has an interior angle of 90 degrees. A right isosceles triangle has both characteristics. The 90 degree angle will be the angle formed by the sides of equal length.
A triangle with 2 equal sides but no right angle?
a triangle with two sides the same length and no right angle
What triangle has 2 sides the same and the same length and a angle of 90 degrees?
An isosceles right angle triangle
Is a triangle with the length of 72425 a right angle triangle?
No way to tell as we don't know an angle or another side.
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 ]
