Table of Contents • Rhombus • IsoscelesTriangle • Altitude • Plane • Inductive Reasoning • Perpendicular Bisector • Obtuse Triangle • Segment • CPCTC • Deductive Reasoning • Corresponding Angles • Parallel Lines • Vertical Angles • Perpendicular Lines • Intersecting Lines • Conditional Statement • Supplementary Angles • Similar Triangles • Congruent Objects • Adjacent Angles • Incenter • Complementary Angles

3. Parallel Lines • Lines that will never meet if extended • If the lines where not parallel than the laptop would just look strange and crooked. The parallel lines ensure that the edge of the screen never meets.

4. Vertical Angles • A pair of angles directly in front of each other • The vertical angle ensures that the D-Pad stays a perfect cross. This helps when playing games. • The purpose of the vertical angle is to keep the angles at 90 degrees. If one angle is 90 degree then so are the rest.

5. Perpendicular Lines • Lines that intersect at a 90 degree angle • If the keys weren’t perpendicular using the arrow keys would feel very uncomfortable. Keeping the arrows at 90 degrees also helps with the rest of the layout of the keyboard.

6. Intersecting Lines • Lines that have one point in common • It is important that these lines intersect because it helps keep the buttons evenly spaced. The dot keeps them evenly spaced because the distance to the point the middle are even on all sides.

7. Conditional Statement • This Mac has an Intel Core i7 2.93 GHz. processor therefore it will be fast • This is not true. If the computer has little RAM then it still won’t run fast. The Random Access Memory is what allows you to run programs.

8. Supplementary Angles • 2 angles that add up to 180 degrees • If the angles were not supplementary than the home button may have not been evenly made. This way the home button can be split down the middle and checked if imperfect

9. Similar Triangles • Similar-Corresponding parts of a shape are proportional • The triangles in the picture are similar because all three sides are proportional. All the sides are similar meaning if the top triangle was extended than it would be congruent with the bottom one.

10. Congruent Objects • Congruent-All corresponding parts are equal • If the two buttons weren’t congruent than the buttons wouldn’t be the same shape or size. That would give the track pad a very weird look.

11. Adjacent Angles • Angles that are next to each other.

12. Incenter • The largest circle inside of a triangle

13. Complementary Angles • Two angles that add up to 90 degrees

14. Rhombus • A quadrilateral that has all 4 sides congruent

15. Isosceles Triangle • A triangle with at least two equal sides.

16. Altitude • Height

17. Plane • A flat two dimensional surface

18. Inductive Reasoning • A method used to establish whether a given statement is true or false.

19. Perpendicular Bisector • A line that cuts another equally and at a 90 degree angle.

20. Obtuse Triangle • A triangle that has one obtuse angle.

21. Segment • A line that has two endpoints

22. Congruent Parts of a Congruent Triangle are Congruent • CPCTC-Once a triangle is congruent then the rest of the corresponding parts are also congruent

23. Deductive Reasoning • A method used to show whether something is true, but follows a certain principle.

24. Corresponding Angles • When a transversal cuts two parallel lines, angles that are on the same side, non-adjacent, one interior and the other exterior.
