Identifying Angle Relationships
Jack is framing the roof of a structure using a triangle and two exterior angles.
A triangle has angles a degrees, b degrees, and c degrees. The exterior angle to a degrees is x degrees.
Which relationships about the interior and exterior angles are true? Check all that apply.
a° + b° + c° = 180°
x° + a° = 180°
a° = c°
a° + c° = 90°
x° + a° = b° + c°
