sin, tan and cos can be defined as functions of an angle. But they are not functions of a triangle - whether it is a right angled triangle or not.
A right triangle has one right angle and two acute angles. Right triangles have a hypotenuse and also two legs. You can use the Pythagorean Theorem to find the hypotenuse, or the two legs of the right triangle, as long as you have the side lengths of the other two sides on the right triangle.
add all of the sides together
Well, honey, the orthocenter of a right triangle is where all three altitudes intersect. In the case of a right triangle, the orthocenter coincides with one of the vertices, specifically the right angle vertex. So, grab your ruler and draw those altitudes to find that sassy orthocenter right at the corner of the right angle.
It is a trigonometric equation for a right triangle, to find a non-right-angle angle. Using SOHCAHTOA, it is the opposite side divided by the adjacent angle
180 minus two known angle = missing angle. Use Pythagoras' theorem to find its missing side.
if the triangle has one right angle in it
The 90 degree angle in a right angle triangle is opposite its hypotenuse.
By using Pythagoras' theorem for a right angle triangle.
It has a 90 degree angle..
right angle!
It is the longest side of a right angle triangle.
The sine of an angle in a right triangle is opposite/hypotenuse, where opposite is the only side that is not adjacent to the angle you want to find the sine of, and the hypotenuse is the side opposite the right angle in the triangle. Just find opposite/hypotenuse.
By using trigonometry that is applicable to a right angle triangle.
Depending on which sides and angle are known you would use one of the trigonometry functions.
It is a right angle triangle and its largest angle is 90 degrees
By using trigonometry that is applicable to a right angle triangle.
It is the longest side of a right angle triangle.
