Indice Lines Bisectors Sexagesimal system and angles Sexagesimal system and time Adding and Subtracting Exercises Lines Plane Geometry Plane Geometry deals with ﬁgures in a plane (circles, lines, polygons. . . ) A line is a set of points extending in two opposite directions without end, It’s a straight one-dimensional ﬁgure with no thickness and extending inﬁnitely in both directions. A line is sometimes called a straight line. Points are said to be collinear points if they lie on a single straight line. A plane is a ﬂat surface that has no thickness and extends without ending in ALL directions. Points are said to be coplanar points if they lie on a common plane. A line segment is a ﬁnite portion of an inﬁnite line. A line segment always has a beginning and an end.Alberto Pardo Milan´s e Angles and Lines

- 6. Indice Lines Bisectors Sexagesimal system and angles Sexagesimal system and time Adding and Subtracting Exercises Lines Perpendicular bisector of a segment and bisector of an angle Lines that intersect in a point are called intersecting lines. Lines that do not intersect are called parallel lines (in the plane). Two lines that lie on top of one another are called coincident lines. Two lines or line segments which are perpendicular are said to be orthogonal (two lines are said to be perpendicular if they meet at a 90o angle). Given two intersecting lines, the point of intersection is called the vertex and the amount of rotation about the vertex required to bring one line into correspondence with the other is called the angle between them.Alberto Pardo Milan´s e Angles and Lines
- 7. Indice Lines Bisectors Sexagesimal system and angles Sexagesimal system and time Adding and Subtracting Exercises Lines One full rotation corresponds to 360 degrees. Half a full rotation is called a straight angle, and a quarter of a full rotation is called a right angle. An angle less than a right angle is called an acute angle, an angle greater than a right angle (but less than a straight angle) is called an obtuse angle, and an angle greater than a straight angle (but less than a full angle) is called a reﬂex angle.Alberto Pardo Milan´s e Angles and Lines

- 12. Indice Lines Bisectors Sexagesimal system and angles Sexagesimal system and time Adding and Subtracting Exercises Sexagesimal system and angles The size of an angle There are several ways to measure the size of an angle, for example using units of degrees: In a complete circle there are three hundred and sixty degrees. You can express angles to any precision using decimal numbers. Example: 30 degrees and a half is 30.5 degrees. There is another way to state the size of an angle, subdividing a degree. The degree is divided into sixty parts called minutes. These minutes are further divided into sixty parts called seconds.Alberto Pardo Milan´s e Angles and Lines

- 14. Indice Lines Bisectors Sexagesimal system and angles Sexagesimal system and time Adding and Subtracting Exercises Sexagesimal system and angles Angles: Degrees, minutes and seconds In a full circle there are 360 degrees, each degree is split up into 60 parts called minutes (each part being 1/60 of a degree), each minute is split up into 60 parts called seconds (each part being 1/60 of a minute). Example: 40 degrees, 20 minutes and 50 seconds is usually written this way: 40o 20 50 . Example: 30.5 degrees is 30o and 30 , because 0.5 degrees are 0.5 · 60 = 30 minutes.Alberto Pardo Milan´s e Angles and Lines

Indice Lines Bisectors Sexagesimal system and angles Sexagesimal system and time Adding and Subtracting Exercises Sexagesimal system and time Time: Hours, minutes and seconds To measure time we can use hours: In a day there are twenty-four hours. You can express time to any precision using decimal numbers. Example: 3 hours and a quarter is 3.25 hours. There is another way to state the amount of time, subdividing an hour. The hour is divided into sixty parts called minutes. These minutes are further divided into sixty parts called seconds. In a day there are 24 hours, each hour is split up into 60 parts called minutes (each part being 1/60 of an hour), each minute is split up into 60 parts called seconds (each part being 1/60 of a minute). Example: 14 hours, 56 minutes and 12 seconds is usually written this way: 14 hr 56 min 12 sec. Example: 3.25 hours is 3 hr and 15 min, because 0.25 hours are 0.25 · 60 = 15 minutes.Alberto Pardo Milan´s e Angles and Lines

- 21. Indice Lines Bisectors Sexagesimal system and angles Sexagesimal system and time Adding and Subtracting Exercises Adding and Subtracting in the sexagesimal system Add in the sexagesimal system You must add or subtract the units separately. But you may need to do some adjusting if the hours end up 24 or more, the minutes end up 60 or more, the seconds end up 60 or more,or less than zero. Adding Add the hours. If the hours are 24 or more, subtract 24 from the hours and add 1 to the days. Add the minutes. If the minutes are 60 or more, subtract 60 from the hours and add 1 to the hours. And so on. Example: 40o 20 50 + 10o 33 6 = 50o 55 56 . Example: 14 hr 20 min 50 sec + 15 hr 43 min 26 sec =29 hr 63 min 76 sec =1 day 6 hr 4 min 16 sec.Alberto Pardo Milan´s e Angles and Lines
