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.Slide4
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. Slide5
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.Slide6
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).Slide7
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.Slide8
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. Slide9
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).
Slide10
Adjacent
Two angles that share a common side and a common vertex ,but do not overlap.Slide11
Similarity
The quality or condition of being similar; resemblance.Slide12
Secant
Secant is the straight line cutting curve: a straight line that intersects with a curve in two or more places.Slide13
Amplitude
Amplitude is the state or quality of being ample, especially as to breadth or width; largeness; greatness of extent.Slide14
Cotangen
tCotangent 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.Slide15
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.Slide16
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.Slide17
Period
An interval of time characterized by the occurrence of a certain condition, event, or phenomenon: a period of economic prosperity.
