All right triangles contain a 90-degree angle. This is the triangle's largest angle, and it is opposite to the longest side. If you have the distances of two sides or the distance of one side plus the measure of one of the right triangle's other angles, you can find the distance of...

Using cosine on a calculator saves a lot of time compared to looking it up in a table, which people did before calculators. Cosine comes from a part of mathematics called trigonometry, which deals with the relationships between sides and angles in right triangles. The cosine specifically deals ...
cosine and tangent are also defined for non-acute angles. To give the full definition, you will need the unit circle. However, in a right triangle, all angles are non-acute, and we

A unit circle defines right triangle relationships known as sine, cosine and tangent. These relationships describe how angles and sides of right triangles relate to one another. Say, for example, we have a right triangle with a 30-degree angle, and whose longest side, or hypotenuse, is a le...
simplify many trigonometric problems. Identities or trigonometric equations with cosine and secant are typically easy to manipulate if you know their relationship. By using the Pythagorean theorem and knowing how to find cosine, sine and tangent in a right triangle, you can derive or calculate ...
In right Fig,if the length of the segment AB is 1,M is the midpoint of the segment AB,and point C divides the segment MB into two partssuch that MC:CB=1:2,then the length of AC is . (英汉词典:length长度;segment线段;midpoint中点;divides…into分为,分成) ...
Find the square of 8 and 14 and add them. b2=82=64c2=142=196b2+c2=64+196=260 Step 4: b2 c2 a2 If the given length forms a right triangle, then the square of the length of the longest side should be equal to the square of the sum of the other two sides. ...
given by the quotient between the opposite side and the hypotenuse of a right triangle. This quotient, as well as other types of quotients, are known as trigonometric ratios. These trigonometric ratios are basic tools used in trigonometry to study right triangles, either to find sides or angl...
