B. Use the Law of Detachment to draw a conclusion.
6. If a figure is a rectangle, then it has four right angles. Figure PQRS is a rectangle.
7. If a quadrilateral is a trapezoid, then It has exactly one pair of parallel sides.
8. If a convex polygon is a pentagon, then the sum of the measures of its interior angles is 540.
9. If an angle is acu.te, then its measure is greater than 0 but less than 90. ABC is an acu.te angle.
10. If two angles are congruent, then their measures are equal. A and B are congruent.
