Which statements can be used to justify the fact that two right angles are supplementary? check all that apply. a. a right angle measures 90°. b. if two angles are complementary, the sum of the angles is 90°. c. if two angles are supplementary, the sum of the angles is 180°. d. a complementary angle is one-half the measure of a supplementary angle. e. a supplementary angle is twice the measure of a complementary angle.

Igure 1 and figure 2 are two congruent parallelograms drawn on a coordinate grid as shown below: 4 quadrant coordinate grid showing two parallelograms. figure 1 has vertices at negative 5, 2 and negative 3, 4 and negative 4, 7 and negative 6, 5. figure 2 has vertices at 5, negative 2 and 7, negative 4 and 6, negative 7 and 4, negative 5. which two transformations can map figure 1 onto figure 2? reflection across the y-axis, followed by reflection across x-axis reflection across the x-axis, followed by reflection across y-axis reflection across the x-axis, followed by translation 10 units right reflection across the y-axis, followed by translation 5 units down
