Parallel Lines �Parallel lines are lines that will go on and on forever without ever intersecting. �If there wasn’t any parallel streets there will be a lot of confusion and accidents.

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.

Vertical Angles �Vertical angles are the angles opposite each other when two lines cross. � I think the person who created the pictures vertical angles to ensure that the costumes had a very enjoyable time on the ride. Also to attract thereal seekers who love high heights.

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).

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.

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.

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. The notation tg x is sometimes also used (Gradshteyn and Ryzhik 2000, p. xxix).

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

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

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

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

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.

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.

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.

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