Hello, this is problem 14 in your geometry textbook.
00:05
This problem deals with trisected angles and congruent angles.
00:12
Since i cannot draw the diagram, we will talk through the pertinent points from the diagram.
00:17
Our given statement is that angle a -e -b is congruent to angle b -e -c, which is congruent to angle c -ed.
00:27
And that's our given.
00:29
So we'll just put given for our reason.
00:34
Now we're going to analyze what the information that they did give us.
00:39
Notice that when you name an angle using three letters, the letter in the middle indicates the vertex of the angle, because more than one angle meets at that vertex.
00:51
All of these angles have the same vertex e.
00:54
They are all part of the same diagram.
00:57
Indeed, if we look at the diagram in your textbook, we can observe that the overall large angle that encompassing all three of them is angle aed.
01:09
So we're going to state the relationship here...
