Estimating Lines and Angles

Estimation of line and angle problems - We set up a course work that requires us to guess the lines and angles drawn on a piece of paper. We have to gather data, analyze it and draw conclusions. METHOD - I drew a line on white paper and drew a corner on another white paper. Then I asked a line and angle estimate from 10 to 15 girls and 15 boys. Since I do not know the size at the moment, I can not give clues.

Please prove the theorem on the line and angle. This theorem assumes that the vertical angle is uniform and when the lateral direction passes through parallel lines the alternate interior angles are uniform and the corresponding angles are uniform and the points on the perpendicular bisector of the line segment are It is exactly equidistant from the end point.

The angular relationship described first is the vertical angle. They are defined as a pair of non-adjacent corners formed with only two intersecting lines. They are called "kiss vs." and always have consistent actions. In the figure below, angles 1 and 3 are vertical, angles 2 and 4. The second relationship is the corresponding angle. They are considered to be in the same place at each intersection. For example, look at angles 1 and 3 below. They are all in the upper left corner. The other pair of corresponding angles are angles 6 and 8, both in the lower right corner.

Before we solve this problem we must determine the relationship between these two angles. Let's answer the above three questions. In question 1, I realized that these angles are not at the same position. Angle 1 is in the upper left corner of the upper intersection and angle 8 is in the lower right corner of the lower intersection so they can not be the corresponding angle. Proceed to Question 2. You can see that the two angles are on both sides of the landscape so you can classify them as alternating angles. In answer to Question 3, both angles are outside the two lines and must be outside the corner. Combining the answers to these questions can conclude that they are staggered external angles.
