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.
