- A trapezoid is a four-sided figure that contains one pair of parallel sides. Which sides of the trapezoid MNPQ appear to be parallel?arrow_forwarda Is it really necessary to construct all three bisectors of the angles of a triangle to locate its incenter? b Is it really necessary to construct all three perpendicular bisectors of the sides of a triangle to locate its circumcenter?arrow_forwardIn Exercises 9 and 10, classify the triangle not shown by considering the measures of its angles. a In XYZ, mX=123. b In RST, mR=45, mS=65 and mT=70.arrow_forward
- A carpenter joins four boards of lengths 6 ft, 6 ft, 4 ft, and 4 ft, in that order, to form quadrilateral ABCD as shown. a What type of quadrilateral is formed? b How are angles B and D related?arrow_forwardDoes the relation is complementary to for angles have a reflexive property consider one angle? A symmetric property consider two angles? A transitive property consider three angles?arrow_forwardIn ABC, the bisectors of the angle are concurrent at point D. If mCAB=64 and mABC=82, find mEDC. Exercises 39, 40arrow_forward
