An angle is a figure formed by two rays that have a common endpoint. The extent of an angle is measured in degrees. Learn more about angles with the help of some solved examples.
Excel has built-in trigonometric functions that make it easy to find the cosine, sine, and tangent of a right-angle triangle — a triangle containing an angle equal to 90 degrees. The only problem is that these functions requireangles expressed in radians, not degrees. While radians, a unit...
Before we measure angles, we need to be able to recognize them. So, what exactly is an angle? An angle is the figure formed when two lines meet at a vertex (or corner). We measure angles using a protractor, and we use units called degrees, which are the units that measure the value...
Angle size calculation refers to the use of geometrical laws and invariants to find out how many degrees an angle is. Therefore, it is different from angle size measurement, which includes the use of a protractor or other tools to come up with the result. Calculating an angle's size demands...
So quadrant 4 will have angles ranging from 270 to 330 degrees (see figure 10). Using the Unit Circle in Practice Remember, the unit circle can be used to find two unknown sides of a right triangle with a 30-degree angle and whose longest side, or hypotenuse, is a length of 7. ...

A right angled triangle has exactly one of its angle values equal to 90 degrees, which is where the Pythagorean theorem formula can be applied. The side opposite the right angle is known as the hypotenuse and will always be the longest side of the right angled triangle. Triangles without a...

The first example creates a path that has a single figure. The figure consists of a single arc. The arc has a sweep angle of –180 degrees, which is counterclockwise in the default coordinate system. The second example creates a path that has two figures. The first figure is an arc foll...
Evaluate these exact values, using the angle identities: 1) \sin 165^{\circ} 2) \cos 195^{\circ} 3) \cos 105^{\circ} How do you figure out the longest side of a triangle? Explain the sine and cosine functions. What is the difference between equilateral and ...
