Practice drawing a line with 2 arrows to show that it continues in both directions:
Draw your line here:
A map is a good example of a plane because it’s a flat surface that goes on in all directions. The points label stores and restaurants.
Here’s a map of a local shopping center in San Jose, CA.
Find and label: Parallel lines, intersecting lines, perpendicular lines
(You may draw lines between points or trace over lines you see in the map.)
Practice drawing a line segment and ray using the line tool with different line ends.
Draw a line segment:
Draw a ray:
Draw line segments and rays on the map.

Use the Polyline tool to create angles.
What kind of angle did I draw? |
|
Draw any type of angle using the polyline tool with arrow endpoints. |
|
Draw the following angles:
Right | Acute | Obtuse | Straight |
| | | |
Explain how you know each angle is drawn correctly: | |||
This is a right angle because... | This is an acute angle because... | This is an obtuse angle because... | This is a straight angle because... |
Draw and label 4 different angles: right, obtuse, acute, and straight
Example:
acute
¼ = 90°
What kind of angle is this? |
|
½ = 180°
What kind of angle is this? |
|
¾ = 270°
1 = 360°
¼ = 90°
What kind of angle do the clock hands show at 1:00? |
|
How can you figure out the number of degrees this angle is? |
|
¼ = 90°
What kind of angle do the clock hands show at 5:00? |
|
How can you figure out the number of degrees this angle is? |
|
½ = 180°
Draw 3 more angles and measure them using the protractor.
