Answer with Step-by-step explanation:
1) Remember:
a.) Included angle of sides AB and AC.
Note that the repeated letter is A. Hence, it is the vertex of the included angle.
Another name for the angle is 3 letters: ∠BAC or ∠CAB)
b) Which is the included side of ∠A and ∠B?
The included side is the combination of the letters of the vertices of the angles adjacent to side.
(write a line over AB to denote that is a side or segment)
2.) Remember:
a) Which two angles are not included between side XY and side YZ?
The non-repeated letters are X and Z. Therefore, they are the vertices of the angles not included.
b) Name two sides not included between ∠X and ∠Z.
Note that the other letter Y is not mentioned, therefore it is the other endpoint of the sides not included.
(Write a line over the letters XY and YZ as symbol of side or segment.)
