Golf Link demonstrates how to identify whether your golf swing plane is correct. The swing plane is the path described by the golf head that controls the direction that the club head is traveling through when it impacts the ball. An on plane swing will have the club head directly traveling towards the target at the point of impact. That and a square face will make a straight shot. If the swing comes inside or below the plane, it will produce a hook shot or a push shot. A swing that comes outs...

When defining fields in FileMaker Pro 10, one has to choose what type of field to decide for a database. There are two fields that accommodate special handling of data. They are time and time stamp fields. When one decides a field under manage>database,there is a option for "type". Under that, there is time and time stamp. The "time" one determines the time while the "time stamp" determines the time and date. This will help in preparing a proper and detailed database system.
Dougsimmsonline shows how to determine whether or not 2 triangles are similar. Not only does he go on to show that they are but he describes step by step how to do the math to find missing angles. He does this process twice to show one set of triangles being similar and show the other set of triangles as not being similar. Doug is using a large computer touch screen as his drawing board to show you how this process is done.
In this tutorial, the author shows how to determine if a point lies on a given line which is in Point Slope Form. To show the method he takes a sample point order pair and an equation of a line in its point slope form. Now he substitutes the value of the x, y order pair and the equation of the line, and solves the equation on both the sides. If both sides match it means that the point lies on the given line, or else it does not lie on the current line. In this video, the instructor shows how ...
This is a tutorial about how to prove the congruency (equality) of two triangles when the values of two angles and an included side of each triangle is given. The author of this video instructs the viewer that it should be first determined whether the values of two angles of one triangle are the same as those of two angles of the other triangle. Then one must seek to determine the equality of sides included in those angles in both the triangles. When it is found that these three values in one...
In this tutorial, we learn how to determine if lines are parallel or perpendicular. You will be given two straight line equations.
