The ideas in this geometry lesson are taken from the Geometry ebook that I sell at MathMammoth.com. This lesson plan does not contain all the problems the Geometry ebook does. Circles

What is a circle? Discuss with your teacher.

1. Draw a radius/diameter from the given point. Look at the example.
|
|
|
|
||
| Here a radius is drawn from the given point. |
a) Draw a radius from the given point |
b) Draw a radius from |
2. Practice drawing circles with your compass. Draw a circle with a 1 inch radius, with 5 cm radius, with 3 cm radius, with 1/2 inch radius.
3. How does the radius of the circles relate to the radius of the
other circles in the pictures?
Practice drawing the figures in your notebook using compass and ruler
only.
a) ![]() |
b) ![]() |
Hint: You will need to make use of the center point of the circles, so
mark them down on
paper after you have drawn any circles. The circles can be bigger or smaller as you
choose. The important thing is to make the pictures look the same.
| 5. Draw a line and then two points on the line. |
|
|
Then draw a circle using one point as a center point
and the other point as a marking the radius. In other words, use the distance between the two
points as the radius. Now draw another circle using the second point
as the center point and the first point as indicating
the radius. Look at the picture. |
|
| a) Now draw a line through the points where the two circles intersect. What do you notice?
b) If you connect the two initial points to the point above them where the two circles intersect (cross), what kind of figure do you get? |
|
7. Draw an equilateral triangle
with the compass and ruler only (don't use the protractor). You can choose
the length of the side. Hint: the idea is the same as in problem 6.
