Learn Alberta: Working with Angles

Review

Line Segment: the part of a line between 2 end points.

Line: a line segment with no end points

3.1 Parallel and Perpendicular Line SegmentsStudent Outcome: I can perform geometric constructions.

- After this lesson you will be able to…
- Draw line segments that are parallel to each other
- Draw line segments
that are at right angles to

each other.

What Are Line Segments?

- Parallel Line Segments
- Describes lines in the same plane that never cross, or intersect
- They are marked using arrows
- The perpendicular distance between
line segments must be the same at

each end of the segment.

- To create, use a ruler and a right triangle, or paper folding

Parallel: two lines or two sides that are the same distance apart and never meet.

Arrows: show parallel sides

Vertex: the point where sides meet or intersect

Student Outcome: I will be able to describe different shapes

What Are Line Segments?

- Perpendicular Line Segments
- Describes lines that intersect at right angles (90°)
- They are marked using a small square
- To create use a ruler and a protractor,
or paper folding.

Perpendicular: where a horizontal edge and vertical edge intersect to form a right angle

OR

when two sides of any shape intersect to make a right angle

Right Angle: 90’ symbol is a box in the corner

Parallel and Perpendicular Line Segments

Figure 1. Airport diagram of Boston’s Logan International Airport with Runway Intersection Lights, Takeoff Hold Lights, and Runway Entrance Lights (in red).

Student Outcome: Airport with Runway Intersection Lights, Takeoff Hold Lights, and Runway Entrance Lights (in red). I will understand and be able to draw a perpendicular bisector.

- On your paper:
- Use a ruler to draw a 6 cm line segment
- Label the endpoints A and B.
- Fold the piece of paper so that the points A and B lie on top of each other.
- Use a ruler to draw a line segment on the crease. Label this line segment CD. Label the point where the two line segments intersect P.
- Use a ruler to measure lengths AP and BP. What do you notice?
- Use a protractor to measure the 4 angles made by the intersecting line segments. What do you notice about these angles.

Student Outcome: Airport with Runway Intersection Lights, Takeoff Hold Lights, and Runway Entrance Lights (in red). I will understand and be able to draw a perpendicular bisector.

- A Perpendicular Bisector:
- cuts a line segment in half and is at right angles (90°) to the line segment.
- If line segment AB is 2
20cm long where

is the perpendicular

bisector?

Example Airport with Runway Intersection Lights, Takeoff Hold Lights, and Runway Entrance Lights (in red).

- Pg. 93, #9
- In some First Nations communities, fish are dried on a drying rack like the one shown. An extra support is needed for this drying rack to hold all the salmon that were caught. Use what you know about drawing perpendicular bisectors to explain how to do this. Include the lengths shown
in the picture in

your explanation

Solution Airport with Runway Intersection Lights, Takeoff Hold Lights, and Runway Entrance Lights (in red).

- Cut a support post that is 1.4 m long. To find the halfway point of the top horizontal pole, divide the length of 3 m in half to get 1.5 m. Place the support at this halfway point. Measure a right angle where the top pole and the support meet in order to position the support perpendicular to the top pole.
