Transformations of a Triangle
11. A rigid transformation is one in which the resulting figure is congruent to the original
figure. There are three types of rigid transformations: translations, reflections, and rotations.
a. Draw coordinate axes. Draw ABC, with vertices at A(3, 1); B(0, 4); and C(1, 5).
b. On a separate set of coordinate axes, draw the image of ABC after a reflection across the
y-axis. Label all points by name (A’, B’, C’) and coordinates.
c. On a separate set of coordinate axes, draw the image of ABC after a rotation of ninety
degrees clockwise around the origin. Label all points by name (A’, B’, C’) and coordinates.
d. On a separate set of coordinate axes, draw the image of ABC after a translation of six
units left and two units up. Label all points by name (A’, B’, C’) and coordinates.
A Chord-ial Relationship
12. A chord is a line segment connecting two points on a circle. A diameter is a chord that
passes through the center of the circle.
a. Draw a diagram showing a chord that is not a diameter of its circle, with a midpoint of the
chord labeled. Identify all statements that would be considered “given.”
b. Write a two-column proof showing the line segment connecting the center of the circle
and the midpoint of the chord must be perpendicular to the chord.
