12. Name the trapezoid with the letters A, B, C and D respectively. 1st Instruction:

13. One segment will never meet the other segment, because they are not destined to each other. Paste the red strips beside each segment. 2nd Instruction:

14. Two segments knew that they have something in common. Both knew that their relationship will work out soon. Paste the green strips to show that they are congruent. 3rd Instruction:

15. The two congruent segments have noticed that the angles opposite them are also congruent. Paste the blue strips to show that the angles are also congruent.   4th Instruction:
