Amy is at City Hall. She wants to meet Matsu at his ending location from Exercise 29. What is the shortest route she can take if she walks along city streets? Is there more than one possible shortest route?

A. 90 degrees b. 45 degrees c. 30 degrees d. 120 degrees

What dimensions can créate more than one triangle ?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
