1 how does the introduction of a new lesson determine whether the two lines are parallel, by definition, in the light of the theory of parallel justice 1. Page 2/total of 15 pages2 and parallel line drawings: 2. Do you remember how to draw parallel lines with straight feet and triangles? Page 3/total of 15 pages 2, parallel line drawings: , parallel line drawings: abccd2 hands on, how do you remember drawing parallel lines with straight feet and triangles? Page 4/total of 15 pages 2, parallel line drawing: , parallel line drawing: 2 hands-on, summation of abcd, do you remember how to draw parallel lines with straight feet and triangles? Method of determination 1 the two straight lines are cut by the third straight line, and if the same arc are equal, the two straight lines are parallel ... Page 5/total 15 pages 3
2. If the two lines are cut off by the third line, can the internal error be used to determine whether the two lines are parallel? If two straight lines are cut off by the third line, then the two lines are paralleled, if the wrong angles are the same ... Page 6/out of 15 pages 3 is simple reasoning, which leads to the determination methods 2 and 3 if the two straight lines are cut by the third line, could it be used to determine the parallels of the two straight lines? Two straight lines are cut off by the third line and, if complementary to the outer angles, the two lines are parallel ... Page 7/total 15 pages of determination method 1 is equal to the azimuth, two straight lines parallel
Is it true that the angles in the diagram draw parallel lines? Page 9/15 e c d b a(1) can be determined by cbe=a which two lines are parallel? Based on what? 4. Consolidating the new understanding, deepening the understanding of example 2, as illustrated by the figure, be is the extension line for ab. Answer: adbc. Two straight lines are parallel according to the same angle. Page 10/total 15 pages e c d b a (2) can be determined by cbe=c which two lines are parallel? Based on what? 4. Consolidate the new understanding and deepen the understanding of example 2 as illustrated by the figure, be is the extension line for ab. Answer: aedd ... Is parallel to two straight lines based on an equal internal error angle. Page 11/total 15 pages ec d b a(3) can be determined by d+a = 180 which two straight lines are equal. Based on what? 4. To consolidate the new understanding and deepen the understanding of example 2, as illustrated, be is the extension line for ab. Answer: aed ... Two straight lines are parallel, based on complementarities with the inner corners. Page 12/1 of 15 pages of this section, what methods of determining parallel lines are you learning? 5. Summarizing the summary (2) can you describe in your own language the process of obtaining parallel-line determination methods? (3) what are the issues to be taken into account in the reasoning that are derived from simple reasoning in determining methods 2 and 3? Page 13/15 textbooks question 5. 2 topics 1 and 4 6
