This document defines and describes different types of angles:
- Acute angles are less than 90 degrees. Obtuse angles are greater than 90 degrees but less than 180 degrees. Right angles are 90 degrees. Straight angles are 180 degrees. Reflex angles are greater than 180 degrees but less than 360 degrees.
- Angles can be calculated based on their relationship to other angles, such as angles around a point adding up to 360 degrees and angles on a straight line adding up to 180 degrees. Vertically opposite angles are always equal.
- When parallel lines are intersected by a transversal, the corresponding angles, alternate interior angles, alternate exterior angles, and interior angles on the same side of the transversal are
A quadrilateral is a shape with four sides, four angles, and four vertices. Quadrilaterals are common in everyday life, appearing in floors, walls, windows, and books. Parallelograms are quadrilaterals where opposite sides are parallel and equal in length; specific types include rectangles, squares, and rhombi. Properties of parallelograms include having diagonals that bisect each other and divide the shape into two congruent triangles.
The document discusses coordinate geometry and the Cartesian coordinate system. It describes how René Descartes proposed using an ordered pair of numbers to describe the position of points on a plane. This allows curves and lines to be described through algebraic equations, linking algebra and geometry. The coordinate plane is defined by perpendicular x and y axes that intersect at the origin. Points on the plane are located using their coordinates (x, y), marking their distance from the two axes. The plane is divided into four quadrants by the intersecting axes.

Kalaripayattu is a 3,000 year old martial art form that originated in South India and is considered the mother of all martial arts. It was developed by the legendary Sage Parasurama and drew inspiration from the strength and movements of animals like lions, tigers, and elephants. Though once shrouded in secrecy, Kalaripayattu laid the foundations for combat for the ancient South Indian kingdoms and is linked as the precursor to other martial arts like kung fu that developed in other parts of Asia.

Euclid was a Greek mathematician from Alexandria known as the "Father of Geometry". His influential work Elements laid out the principles of Euclidean geometry through a small set of axioms and deduced many other geometric principles through logical proofs. Elements was used as the main geometry textbook for over 2000 years. Euclid introduced deductive reasoning and the axiomatic method to geometry which established it as the first example of a formal axiomatic system.
Coordinate geometry represents points on a number line with real numbers. The number line places positive numbers to the right of zero and negative numbers to the left.
The Cartesian coordinate system uniquely determines points in two or three dimensional space using perpendicular x and y axes intersecting at the origin. René Descartes developed this system, linking algebra and geometry by describing curves and lines with equations.
The coordinate plane has perpendicular x and y axes. Points are located using their x and y coordinates, which represent horizontal and vertical distances from the origin. The plane is divided into four quadrants numbered counter-clockwise from the top right. Ordered pairs notation (x,y) specifies a point's location by listing the x coordinate first.

Triangles can be classified based on the number of congruent sides. There are three types of triangles: scalene (no congruent sides), isosceles (at least two congruent sides), and equilateral (three congruent sides). Heron's formula provides a way to calculate the area of any triangle using the lengths of its three sides. The formula is: Area = √(s(s-a)(s-b)(s-c)), where s is the semi-perimeter (sum of sides divided by 2). The document also presents a researched formula for calculating the area of an equilateral triangle using only the length of one side.
Euclid's Geometry outlines Euclid's influential work on geometry from around 300 BCE. It defines Euclidean geometry as the study of plane and solid figures using axioms and theorems.

8. Types of
Quadrilaterals
• A closed plane figure bounded
by four straight lines is called a
quadrilateral.
• A quadrilateral has four
vertices.
• The line segments joining the
opposite vertices are called its
diagonals.
• A quadrilateral has 4 angles.
The sum of its interior angles is
360 ⁰.
8
9. • Parallelogram:
If the line segments in each pair
of opposite
sides of a quadrilateral are
parallel, then the
quadrilateral is called a
parallelogram.
• Rhombus:
If all the sides of a parallelogram
are congruent,
then it is called a rhombus.
9
10. • Rectangle:
If all the angles of a parallelogram are right
angles,
then the quadrilateral is called a rectangle.
• Square:
If all the sides of a rectangle are congruent,
then it is
called a square.
• Trapezium:
If in a quadrilateral, line segments in one pair of
opposite side are parallel and the opposite
sides in the
other pair are not parallel, then the
quadrilateral is
called a trapezium.
10
11. Special Kinds of
Quadrilaterals-kite
• If in a quadrilateral,
two pairs of
adjacent sides are
equal, then it is
called a kite.
• The diagonals of a
kite are not equal
but intersect each
other at right
angles.

12. You have learnt
• A closed plane figure bounded by four straight lines is called a
quadrilateral.
• The sum of the interior angles of a quadrilateral is 360 ⁰.
• If both pairs of opposite sides of a quadrilateral are parallel, then the
quadrilateral is a parallelogram.
• If in a parallelogram, all sides are equal, then it is called a rhombus.
• If in a parallelogram, one of the angles is a right angle, then it is called a
rectangle.
• If in a parallelogram, one of the angles is a right angle and all sided are
equal,
then it is called a square. 12
