104 In the diagram below, PA and PB are tangent to
circle O, OA and OB are radii, and OP intersects
the circle at C. Prove: ∠AOP ≅ ∠BOP
105 The coordinates of the vertices of ABC are
A(1,2), B(−4,3), and C(−3,−5). State the
coordinates of A' B' C', the image of ABC after
a rotation of 90º about the origin. [The use of the
set of axes below is optional.]
106 In the diagram below, A′B′C ′ is a transformation
of ABC, and A″B″C ″ is a transformation of
A′B′C ′.
The composite transformation of ABC to
A″B″C ″ is an example of a
