Plotting a bearing on your map. Castle Rock Quad. You have just located the first point in an orienteering course. The clue indicates that the next location is 1.2km away on a bearing of 286° True. Your GPS indicates that you are currently at 586362m E 4113408m N.

Module 3B:. Geometric Relationships. Special Pairs of Angles: Complementary Angles - Angles that have a sum of 90 degrees. 25 + 65 = 90 Supplementary Angles- Angles that have a sum of 180 degrees. 140 + 40 = 180. 65˚. 25˚. 140˚. 40˚.

Lesson 3. Parallel Lines. Definition. Two lines are parallel if they lie in the same plane and do not intersect. If lines m and n are parallel we write. p. q. p and q are not parallel. m. n.

Angles and Parallel Lines. Lesson 2-4. Transversal. Definition: A line that intersects two or more lines in a plane at different points is called a transversal. When a transversal t intersects line n and m , eight angles of the following types are formed: Exterior angles

5.3 Systems of Linear Equations in Three Variables. solution. ordered. triple. A of a system of linear equations in three variables is an of real numbers that satisfies all equations of the system. In other words, the solution is the point of of three planes. intersection.

Bingo Answers. Fill in all 25 spaces on your Bingo card, using any of the given answer choices. Do NOT Repeat any choices. What is the equation of the line that crosses the y-axis at (0,4) and has a slope of 2?. What is the equation of the line that passes through (1,5) and (3,9)?.

INFORMATION TECHNOLOGY. Data Capture and Input Methods. Data Capture. Data capture means obtaining data for a computer. Collecting documents to be typed in Making measurements and keying in Asking people to fill in questionnaires

Parallel and Perpendicular Lines. Parallel Lines. Two lines with the same slope are said to be parallel lines. If you graph them they will never intersect. We can decide algebraically if two lines are parallel by finding the slope of each line and seeing if the slopes are equal to each other.

3.4 Proving Lines are Parallel. Mrs. Spitz Fall 2005. Standard/Objectives:. Standard 3: Students will learn and apply geometric concepts Objectives: Prove that two lines are parallel.

Pairs of Lines. Lesson 2-3. Parallel Lines. Parallel lines are coplanar lines that do not intersect. Arrows are used to indicate lines are parallel. The symbol used for parallel lines is ||. In the above figure, the arrows show that line AB is parallel to line CD.

Bubble Chamber Detective Part I. Altered from the original at http://teachers.web.cern.ch/teachers/archiv/HST2005/bubble_chambers/BCwebsite/index.htm. Physicists learnt about hundreds of new particles by examining the trails they made in bubble chambers. This analysis uses a few rules;
