Answer:
A)The points are D,E,G,A,B and C.
B)The other names of line r is, AB, BC and AC.
C)DE and DG.
D)M means the plane on which all the above lines, line segments and rays lie on.
E)∠EDG and ∠GDE
Step-by-step explanation:
A) All the points are those which are represented by a dot. The points are D,E,G,A,B and C.
B) The other possible names of a line can be given with the points on the line.
The other names of line r is, AB, BC and AC.
C) The ray is a point at one side and a arrow head line on other side, finite on one side and infinite on other side.
Thus, the rays are DE and DG.
D)M means the plane on which all the above lines, line segments and rays lie on.
E) ∠1 can be represented as ∠EDG and ∠GDE. (D in center as it is the focus, where the 2 lines meet.)
