The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. DEFINITIONS
Circle
– A set of points of equal
distance from the center.
Circumference – The perimeter of the
circle.
Diameter– A chord that passes
through the centre.
Radius – Half of the diameter.
Chord – A line segment that joins two
points on the circle.
3. Tangent - A straight line that touches
the circle at a single point.
Arc – Any part of a curve of a circle.
Major Arc – The larger arc.
Minor Arc – The smaller arc.
CentralAngle – An angle that has it’s
vertex at the center, two radii form the
arms of the angle
4. Inscribed Angle – An angle that has it’s
vertex on the circle and two chords form
the arms.
Intercepted Arc - That part of a circle
that lies between two lines that intersect
it.
Subtended – Closed off by an arc or line
Segment – A part of a line or curve
between two points.
Cyclic Quadrilateral - A quadrilateral
whose vertices all lie on a single circle.
5. RULE #1
The perpendicular line from the centre of a circle
to a chord bisects the chord.
6. RULE #2
Aninscribed angle is subtended by a diameter
than all the angles should equal to 90°
90°
90°
90°
90°
7. RULE #3
If
an inscribed angle and a central angle are
subtended by the same arc then the inscribed
angle is half the central angle.
68°
24°
48°
24°
back
8. RULE #4
All
perpendicular bisectors pass through the
center. Both are diameters of the circle.
9. RULE #5
Whentwo or more inscribed angles are
subtended by the same arc then all angles are the
same.
40° 20°
40°
10. RULE #6
If
two chords in a circle are parallel then they
share the same angles.
30°
30°
50° 50°
50° 50°
30°
30°
11. RULE #7
Iftwo tangents are drawn from a common point,
exterior to a circle then the length of the tangent
lines should be the same.
90°
90°
12. RULE #8
When two angles are opposite from each other in
a cyclic quadrilateral, then they should be
supplementary.
70° 84° <ABC + CDA = 180°
96° + 84° = 180°
<BCD + <DAC = 180°
110° + 70° = 180°
110°
96°
back
13. RULE #9
Whenan angle is formed between a tangent line
and a chord then it is equal to the inscribed angle
on the opposite side of the chord.
70°
14. RULE #10
Aconvex polygon with n sides can be divided into
(n-2) triangles
# OF TRIANGLES = n-2 SUM OF INTERIOR <‘s
# OF TRIANGLES = 5-2 = 180(n-2)
# OF TRIANGLES = 3 =180(5-2)
=180(3)
=540
The sum of the interior angles of a polygon with
n sides = 180(n-2)
