This provides the answers and solutions for the Put Me in, Coach! Practice boxes, sorted by sections. . We`ve researched the most important things to keep in mind when buying a 3D printer and selected the best printers of 2020 based on your needs. 4. Sentence 10.9: If two lines are cut by a cross-section so that the alternating outer angles are congruent, then these lines are parallel. Given:? ABC is a rectangular triangle, and ? B is a right angle. Data: The lines l and m are cut by a transverse t, with ?1 ~= ?3. 5. Sentence 15.9: The opposite angles of a parallelogram are congruent. . 6. No, a triangle with these lateral lengths would violate the inequality of the triangle. Transitive property: Yes? ABC ~=? DEF and ? DEF ~=? RST, then? ABC ~=? RST.

2. If? Comic book shares? ABC from two angles, ? ABD and ? DBC, then m?ABC = m?ABC – m?DBC. . ? To and ? B are complementary and ? C and ? B are complementary. ? To and ? B are additional angles and ? A is a right angle. 3rd movement 15.5: In a dragon, a pair of opposite angles is congruent. Trapezoidal ABCD with its XB CY showed four heights. Symmetric property: If? ABC ~=? DEF, then? DEF ~=? ABC. . 4th movement 15.6: The diagonals of a dragon are vertical, and the diagonal opposite to the congruent angles halves the other diagonal. 3.

Sentence 11.3: The measurement of an outer angle of a triangle is the sum of the dimensions of the two non-adjacent inner angles. . 4. Adding a right angle is a right angle. 6. If? P ~=? R and M is the center of PR, as shown in Figure 12.17, then? N ~= ?Q. 3rd sentence 10.5: If two parallel lines are cut by a cross section, then the outer angles on the same side of the transverse are complementary angles. 2. Proof: If AC ~= CD and ? ACB ~=? DCB, as shown in Figure 12.5, then? ACB ~=? DCB…
