a) OM, ON, OP, OQ are radii; MN, PQ are diameters.

b) OA, OB are radii; AB is the diameter.

Solving Exercise 2 on page 111 of Math textbook 3

Exercise prompt:

Please draw circles with:

a) Center O, radius 2cm

b) Center I, radius 3cm.
Answer:

Students use a compass to draw.

Solving Exercise 3 on page 111 of Math textbook 3

Exercise prompt:

a) Draw radius OM, diameter CD of the following circle:

b) Which statement is correct, which one is incorrect?

The length of line segment OC is longer than the length of line segment CD

The length of line segment OC is shorter than the length of line segment OM

The length of line segment OC is equal to half the length of line segment CD.
Answer:

b) The length of line segment OC is longer than the length of line segment CD (false)

The length of line segment OC is shorter than the length of line segment OM (false)

The length of line segment OC is equal to half the length of line segment CD (true).
