Assessment 1
3. Work cooperatively
through Lesson 1-1
You will be able to
identify, describe, and
name points, lines, line
segments, rays,
and planes using
correct notation
Objective 1
To identify and name
angles
Objective 2
Collinear and Coplanar
Collinear points are
points that lie on the
same line.
Point 𝐴 is between
points 𝑅 and 𝑁.
Coplanar points are
points that lie on the
same plane.
Exercise 1
Which numbered angle is the same as
∠𝐴𝐵𝐶? Explain.
Exercise 2
Explain why you
can’t call ∠𝐹𝐷𝐺
simply ∠𝐷.
