3. Parallel Lines
Parallel lines are lines that will go on and on forever without ever intersecting.
If there wasn’t any parallel lines there will be a lot of confusion and chaos in this world.

4. Two Congruent Objects
Two objects are congruent if they have the same dimensions and shape.
If the shape didn’t have two congruent objects then the shape would have one side that’s longer and the other side smaller and it will not be even

5. Vertical Angles
Vertical angles are the angles opposite each other when two lines cross.
A vertical line is used to determine if a graph represents a function.

6. Perpendicular Lines
Perpendicular lines are lines that are at right angles (90°) to each other.
Two non-perpendicular lines form obtuse angles (greater than 90 degrees) or acute angles (less than 90 degrees).

7. Sine
The length of the opposite side divided by the length of the hypotenuse.
The sine function is a function of an angle. In a right triangle, sine gives the ratio of the length of the side.

8. Cosine
The length of the adjacent side divided by the length of the hypotenuse.
The cosine function has a number of properties that result from it being periodic and even.

9. Tangent
Making contact at a single point or along a line; touching but not intersecting.
The tangent function where sin x is the cine function cos x and is the cosine function.

10. Adjacent
Two angles that share a common side and a common vertex ,but do not overlap.

11. Similarity
The quality or condition of being similar; resemblance.

12. Secant
Secant is the straight line cutting curve: a straight line that intersects with a curve in two or more places.

13. Amplitude
Amplitude is the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent.

14. Cotangent
Cotangent is a ratio of adjacent to opposite side: for a given angle in a right triangle, a trigonometric function equal to the length of the side adjacent to the angle divided by that of the side opposite the angle.

15. Diameter
Diameter is a line through center of circle: a straight line running from one side of a circle or other rounded geometric figure through the center to the other side, or the length of this line.

16. Cosecant
Cosecant is a ratio of hypotenuse to opposite side: for a given angle in a right triangle, a trigonometric function equal to the length of the hypotenuse divided by that of the side opposite the angle.

17. Period
An interval of time characterized by the occurrence of a certain condition, event, or phenomenon: a period of economic prosperity.
