  4. Look at three pairs of lines below! www.ajwmathematics.wordpress.com

  5. Line Position 1. Parallel Lines Parallel lines are lines in a plane which do not meet. Or to be said that two lines in a plane that do not intersect or touch at any point. www.ajwmathematics.wordpress.com

  6. 2. Intersecting Lines Two or more lines that meet at a point www.ajwmathematics.wordpress.com

  7. 2. Perpendicular Line • A line is said to be perpendicular to another line if the two lines intersect at a right angle Explicitly, a first line is perpendicular to a second line if 1) the two lines meet and 2) at the point of intersection the straight angle on one side of the first line is cut by the second line into two congruent angles www.ajwmathematics.wordpress.com

  12. Example Draw a line l through A(-3, 5) which is parallel to the x-axis and perpendicular to the y-axis! Untukmempermudahpengerjaandapatmenggunakanaplikasi program Geo Gebra www.ajwmathematics.wordpress.com

  13. Latitude and Longitude Latitude Latitude is a virtual line that circles the earth. It consists of north and south latitude. The reference line of latitude is the Equator (0 °). Latitude determines the differences of climate zones on Earth. Longitude Longitude is a line drawn from the north pole to the south pole. The reference line of longitude is a line that passes through Greenwich in the England or called meridians. It consists of west and east longitude. Longitude determines time difference of each cities in the earth's surface. www.ajwmathematics.wordpress.com
