We need to look at a diagram with lines, rays and points, and see which statements are true.
The true ones are:
- CE is contained on line m
- Ray AD is the same as ray AC.
- ∠ECB is created from CE and CB.
To find this, we need to analyze each statement.
1) "CB is contained on line n."
CB defines the ray that passes through points C and B, and we can see that neither of these points is on line n, thus this statement is false.
2) CE is contained on line m.
This is true, both points C and E are on line m.
3) Ray BC is the same as ray CB.
False, ray BC is has the starting point at B, while ray CB has the starting point at C. In the diagram, the only graphed ray is CB (because it starts at point C).
4) Ray AD is the same as ray AC.
True, thus both of these rays start at the same point, and both D and C are collinear, thus we can see that the ray AD contains point C, and the ray AC contains the point D.
5)∠EAD is created from AE and DA.
∠EAD is the angle where point A is the vertex and AE and AD are the two rays that define the angle.
Note that in the statement we have DA instead of AD, which is different, so the statement is false.
6) ∠ECB is created from CE and CB
Similar to before, but now the two rays are correctly written, so this is true.
