Answer:

The pairs of lines are nothing but the two lines, which may be intersects or parallel or perpendicular as shown below: Angles: The region between two infinitely long lines pointing a certain direction (ray) from a common point (or vertex) is termed as an angle. ... The symbol for an angle is “ ∠ ”.The first concept was used by Eudemus, who regarded an angle as a deviation from a straight line; the second by Carpus of Antioch, who regarded it as the interval or space between the intersecting lines; Euclid adopted the third concept, although his definitions of right, acute, and obtuse angles are certainly ...troubleshoot potential server malfunctions, and to gather use and demographic information.

Activity:

Exploring

Students work in small groups to explore lines. Each group will have a laser pointer and a journal to record their discoveries. Groups are taken outside and given tasks to complete with the laser pointer such as "point the laser into the open sky" or "stand 10 feet from the tree and point the laser directly at it." Task cards should include directions to create...

line

ray

parallel lines

perpendicular lines

(groups can combine to create parallel and perpendicular lines)

After each task, groups are to record their observations of the lasers (line). Have the groups discuss their discoveries. Use this demonstration to explain the difference between a line (never ending), a line segment, a ray, parallel and perpendicular lines.Watch BrainPOP's videos on Parallel and Perpendicular Lines and Angles, then discuss.Students are put into groups and given one of the following terms on a card...

line segment

ray

parallel lines

perpendicular lines

obtuse angle

right angle

acute angle

Groups then use their bodies to demonstrate each term and then take a picture of the formation. They create as many different configurations of the term as they can, taking a picture of each one. When finished, students pull their pictures into Photo Grid. After all groups are finished have them take turns sharing their collages. Students try to guess which term each group had and explain how they knew.

Step-by-step explanation:

Students work on iXL 4th grade, lessons P.13 and P.29, to practice their line and angle skills.Put students into groups and give them a check-off list of the terms used during this lesson. Take the groups outside and ask them to find creative examples of each term in the environment and photograph them. Once the groups are finished, have them use Educreations to create a presentation of their pictures. Students should use the voice recorder, pen, and typing tool to illustrate where each term is in the picture and prove that it is an example of the term. Share presentations with the class and discuss.
