Step 1: Getting Started
Go to Mr. Newton’s Website → NetLogo for Geometry
Construct a line that contains the points D ( -2, 1) and X ( 0, -3).
Construct a line segment that contains M ( 2, -10 ) and N ( 1, 5 ).
Label the points.
Remember to label
everything! Check on
In quadrant 1: Draw a circle
In quadrant 2: Draw a triangle
In quadrant 3: Draw a trapezoid
In quadrant 4: Draw a frowny face
Construct a line segment with endpoints A and D.
A( 4, 7 )
D ( -3, -6 )
Find the length of segment AD.
Use the distance
formula or the
Pythagorean Theorem!
Construct a right triangle ABC with vertices
A ( 2, 3 ) B ( 7, 3 ) and C ( 7, -3)
Find the length of the hypotenuse.
Find the Perimeter.
You can use the
Challenge: Find the Area.
Pythagorean Theorem
on this problem!
Construct a line that contains A ( 3, -4 ) and B ( 8, -1).
Construct another line which contains C ( 5, 5 ) and is parallel to the
first line.
Parallel Lines have the
same slope!!
Construct a line that contains C ( -4, 3 ) and E ( 1, 1 ).
Construct a line perpendicular to the first line.
Label the points.
Perpendicular Lines
intersect at a right angle!
Construct the following rays:
C ( -4, 2 )
D ( 5, 5 )
E ( 1, -3 )
Label the points.
Which type of angle is <CDE?
Find a point which exists on the interior of <CDE.
Find a point which exists on the exterior of <CDE.
The vertex is always the middle
letter in the angle name!
In quadrant 1: Draw an angle that measures approximately 70°.
In quadrant 2: Draw an angle that measures approximately 130°.
In quadrant 3: Draw an angle that measures approximately 180°.
In quadrant 4: Draw a right angle.
Remember how big a right
angle is and the rest is easy!
In quadrant 1: Construct a square with side lengths of 4.
In quadrant 2: Construct a square with perimeter 28.
In quadrant 3: Construct a rectangle with area 20 and perimeter 18.
the top right! Then it goes
counter clockwise!
Draw a star with 5 points using 10 segments.
Since it has 10 sides, this star is
a decagon!
