8. two angles that add up to 180 degrees
9. line or line segment that is perpendicular and passes through the midpoint of another line segment
11. a chromosomal segment breaks off and flips around backwards
12. mutations that cause death, usually before birth
13. line or line segment that separates an angle into two equal parts

3. two angles that add up to 90 degrees
4. A healthy copy of a gene is introduced into defective cells
5. the loss of a piece of chromosome due to breakage
6. the middle of a line segment, creates two equal parts
7. a change in the nucleotide base sequence of a gene or DNA molecule
