(05.06a)angle abc is formed by segments ab and bc on the coordinate grid below:
a coordinate plane is shown. angle abc has vertices at 3 comma 4 and 5 comma 3 and 3 comma 2 and measures 53.13 degrees.
angle abc is rotated 90 degrees counterclockwise about the origin to form angle a′b′c′. which statement shows the measure of angle a′b′c′? (05.06a)the figure below shows the letter t and four of its transformed images—a, b, c, and d:
a letter t is formed on the coordinate plane with endpoints negative 5 comma negative 1, negative 3 comma negative 1, and negative 4 comma negative 3. figure a has endpoints negative 5 comma 3, negative 3 comma 3, and negative 4 comma 1. figure b has endpoints negative 1 comma 2, negative 3 comma 2, and negative 2 comma 4. figure c has endpoints 3 comma negative 1, 4 comma negative 3, and 5 comma negative 1. figure d has endpoints 2 comma 1, 3 comma 3, and 4 comma 1.
which of the four images was formed by a reflection of the letter t?
