Two rays are opposite rays in geometry if they have a common initial point and form a straight line. Essentially, these rays point in opposite directions. The common initial point is also called the end point of a ray.Know More
The opposite arms of a straight, 180-degree angle are an example of opposite rays.
A ray is a set of infinite points. It has length but no width. It stretches indefinitely in one direction only. Two opposite rays stretch indefinitely in both directions. All points on these two rays are collinear points.
A ray is a subset of a line. It always lies in a plane. Two opposite rays are subsets of the line that they form.Learn more about Data Graphs
An 180 degree angle formed by two opposite rays is called a straight angle. A ray is a straight line that moves indefinitely in one direction away from a given point. The rays move in opposite directions away from the vortex or meeting point where the angle is formed.Full Answer >
The main difference between a histogram and a bar graph is that a histogram displays quantitative data while a bar graph displays qualitative data. Quantitative data is numerical and can be measured by counting. Qualitative data refers to a trait or characteristic.Full Answer >
An ogive graph is a smooth S-shaped curve that is used in statistics. The graph is obtained by plotting the values of cumulative frequency against the upper boundary points of the class intervals.Full Answer >
The primary advantage of using a graph or chart in a presentation is that they help the audience to visualize the point of the presentation. Graphs emphasize the main point, make the data more convincing, provide a compact way of presenting information and help audiences stay engaged. Disadvantages of graphs include being time consuming to construct and costly to produce. They also require technology that some may lack.Full Answer >
