Question
AB has endpoints A(– 5, – 10) and B(– 1, 2). CD has endpoints C(3, 5) and
D(12, -3). Determine whether the two segments are congruent by finding
1.
the length of each segment, expressing each length as a radical in
simplest form, and using the definition of “congruent”.

angle. Find the measure of each angle.
M is the midpoint of AC . A has coordinates (– 5, – 7) and M has
coordinates (0, 4). Find the coordinates of C.
N is the midpoint of MO , MN = 4x + 6, and NO = 7x - 9. Find NO.
TRUE or FALSE
a. ALL adjacent angles are vertical angles.
b. If two complementary angles are equal in measure, then each
measures 45°.
