The document outlines a lesson plan on teaching students about pairs of angles formed when parallel lines are cut by a transversal. It includes the objectives, subject matter, materials, and a step-by-step procedure using the 5A's method of teaching. The procedure involves students drawing parallel lines cut by a transversal, identifying and defining different pairs of angles, including alternate interior angles, alternate exterior angles, and corresponding angles. Students are then given activities to practice identifying these pairs of angles and an assignment to measure angles in a drawing.
Area and circumference of circles
This document defines key terms and formulas related to circles, including circumference and area. It defines a circle as all points equidistant from a given center point. The radius is the distance from the center to the edge, and the diameter runs through the center. Circumference is defined as the distance around the circle and is calculated using either C=2πr or C=πd. Area is calculated as A=πr^2. Several examples are provided to demonstrate calculating circumference and area using these formulas.

All about-angles [final] (1)
- The document discusses different types of angles including right, acute, obtuse, and reflex angles. It provides definitions and examples of each type of angle.
- Readers are guided through interactive quizzes and examples to learn how to identify different angles based on their measure and appearance.
- The project asks readers to make an angles collage that divides a page into sections for the different angle types and includes examples of each.
Case artifact 1
There are several types of angles including acute, right, and obtuse angles which are defined by whether they are less than, equal to, or greater than 90 degrees respectively. Rays have one endpoint and extend to infinity, while straight angles measure exactly 180 degrees, the same as a straight line. In summary, angles can be classified based on their degree of rotation compared to right angles of 90 degrees.
Mouse mischief angles
An acute angle measures less than 90 degrees, an obtuse angle measures more than 90 degrees, and a right angle measures exactly 90 degrees. The document provides examples of different types of angles and asks the reader to identify, draw, and classify various angles as acute, obtuse, or right.
1.2 Poolroom Math
This document provides information about angles:
- A ray is part of a line with one endpoint that extends indefinitely. An angle is formed by two rays with a common endpoint called the vertex.
- To measure an angle with a protractor, place the protractor's center on the vertex and line up one side with 0 degrees, reading the measure of the angle along the other side.
- Congruent angles have the same measure and are denoted with a congruent sign (≅). Bisected angles form two congruent angles. Angle names use the vertex letter and not ticks.
- Types of angles include acute (<90 degrees), right (90 degrees), obtuse (>90<180 degrees
Family of Circle
This document introduces several circle theorems including:
1. Angles subtended by the same chord are equal.
2. The angle subtended by the same chord at the centre is twice that at the circumference.
3. The opposite angles of a cyclic quadrilateral add up to 180 degrees.
It also discusses properties such as an angle in a semi-circle being 90 degrees and the radius and tangent being at right angles.
3 Geometry Angles
* There are 3 angles in a triangle
* The sum of the angles is 180°
* We are given: Angle 1 = 85°, Angle 2 = 60°
* So: Angle 1 + Angle 2 + Angle 3 = 180°
* 85° + 60° + Angle 3 = 180°
* 145° + Angle 3 = 180°
* Angle 3 = 180° - 145° = 35°
Therefore, the missing angle is 35°.

The Evolution and Impact of OTT Platforms: A Deep Dive into the Future of Ent...
This presentation provides a thorough examination of Over-the-Top (OTT) platforms, focusing on their development and substantial influence on the entertainment industry, with a particular emphasis on the Indian market.We begin with an introduction to OTT platforms, defining them as streaming services that deliver content directly over the internet, bypassing traditional broadcast channels. These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.
