1- Check the correct alternatives (can be more than one). (Dolce & Pompeu)

If two segments are adjacent, then they are consecutive. If two segments are adjacent, then they are collinear. If two segments are collinear, then they are adjacent. If two segments are collinear, then they are consecutive. If two segments are consecutive, then they are adjacent. (UNB 1990) The bisectors of two adjacent and complementary angles form an angle of 45°. If two segments are consecutive, then they are collinear.

2- Check the correct alternatives (can be more than one). (Dolce & Pompeu)[br]

Two segments opposed by the vertex are consecutive. Two consecutive segments are adjacent. Two adjacent segments are opposed by the[br]vertex. Two adjacent segments are consecutive. Two segments opposed by the vertex are[br]adjacent.

3- (Dolce & Pompeu-adapted) Consider that the supplement of three times the complement of[br]half of an angle is equal to three times the complement of that angle. Then the angle measures:[br][br][br]

90º 80º 70º 50º 30º

4- (Dolce & Pompeu-adapted) The bisectors of two consecutive angles form an angle of 52º. If one of them measures 40º, then the other measures:

5- (Dolce & Pompeu-adapted) The angles [math]\alpha[/math] and [math]\beta[/math] and are opposed by the vertex. The angles are[br]measured in degrees. The first angle is 9x-2 and the second is 4x + 8. Determine these angles. [br]
