This video in the Education category will show you how to use a protractor to measure an angle. This video is from Brightstorm. In Geometry it is important to know how to measure an angle. This is a very simple and easy process. In order to measure an angle, you will need a protractor. Every protractor has a base and a center point marked on the base. You will put the center point on the vertex of the angle. Then align the base line of the protractor perfectly on one side of the angle. Now ch... ### How To: Understand the Rule of Corresponding Angles

This video explains about the rule of corresponding angles. When measuring the angle between the parallel lines (i.e.) Line1 and Line2 across the straight line. The angle A and angle B are equal. The angle C and angle D are equal. The angle E and angle F are equal. Finally angle G is equal to angle F. So, the angle between the parallel lines in all the angles are equal. Hence, this is the rule of corresponding angles. This video is very useful to basic high school geometry courses. Correspond... ### How To: Find an angle using alternate interior angles

In this video tutorial, viewers learn how to find an angle using alternate interior angles. Make sure that the angles are alternate interior angles. Alternate interior angles are angles that are on the inside of the parallel lines, and on the opposite side of the transverse. The transverse is the line that passe through the two parallel lines. If both angles are inside the line and are opposite to the transverse, then they are alternated interior angles. If you know two angles are alternate i... ### How To: Find an inscribed angle w/ corresponding arc degree

In this tutorial the instructor shows how to find an inscribed angle when its corresponding arc degree is given. He shows how to do this with the help of an example. He states that the angle of arc degree is always twice the angle of its corresponding inscribed angle. So now to find out the angle of the inscribed angle we just need to divide the corresponding arc degree by two. In this video the instructor shows a simple way to find the inscribed angle when its corresponding arc degree is given. ### How To: Find a central angle with a radius and a tangent

mathproblemgenerator.com provides a video about how to find a central angle with a given radius and a tangent. The angle at the intersection of the radius and the tangent is equal to 90 degrees. The second angle is also given in the problem. So the central angle is equal to 180 minus (90 plus the other angle given). In the video, the given angle is 54 degrees, making the equation = 180 - (90 + 54). Therefore the central angle is equal to 36. ### How To: Mod a Flip UltraHD video camera for telephoto and wide-angle lenses

This video instructs you on how to draw angles in geometry. The instructor begins by showing you 4 example angles you can create. He then draws a straight line that can be linked to any of the other four angles. The first example of an angle shown is 180 degrees. He draws a line at 50 degrees and then he continues to draw a 90 degree angle. The instructor varies whether he uses the left or right side of the protractor. He ended by noting some angles will be larger than the protractor. ### How To: Understand angle relationships

In this tutorial, we learn how to understand angle relationships. Start out by drawing an angle out and looking at the different parts of it. From here, you will start to find where the different angles are. Linear pairs equal 180 degrees and are on a straight line. Once you learn this, you can write them out on the paper. Supplementary angles equal 180 degrees as well. Two angles that add up to 90 degrees are complimentary angles. Once you learn the relationships between angles, you can bett... ### How To: Understand the rule of vertically opposite angles

In this video we learn how to understand the Rule of Vertically Opposite Angles. This says that when two straight lines cross it produces vertically crossed lines that must have congruent angles. Because the lines are straight this has to happen. Remembering the rule "supplementary" you will be able to calculate the angle of A and B in the equation. Prove what each of the angles are using the different rules and then move onto the other two angles. Angle C can be figured out by knowing that i... ### How To: Prove an inscribed angle is half of a central angle

Watching this video will make you feel like your back in the classroom but rather comfortably from your home. ### How To: Find a missing angle inside of a triangle

Are math problems getting you down? Well this should be of some help. Here is how to find a missing angle inside of a triangle. Now the first thing to remember when solving this type of question is that the sum of all the three angles inside a triangle is equal to 180 degrees. Therefore, whenever we have two of the three angles inside the triangle, all we have to do in order to obtain the missing angle is to add up the two known angles and subtract the total from 180 and we will get the missi... ### How To: Find an angle when there are pairs of parallel lines

Consider two pairs of parallel lines, one pair horizontally and another is inclined from vertical position. If one of the four angles is given, then the other three angles can be easily identified. First select the angle which is down to the known angle, it will be same as first one. Then according to the law, that a straight lines consists of 180 degrees. For example if the known angle is 114 degrees, the unknown angle will be 180-114= 56 degrees. ### How To: Calculate the optimal angle for a projectile
