In plane geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.[1] Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane. Angles are also formed by the intersection of two planes in Euclidean and other spaces. These are called dihedral angles

Angles is an annual online magazine of exemplary writing by MIT students. All of the works published in Angles since its first edition in 2008 were written by students in the introductory writing courses. These courses, designated as CI-HW (Communications-Intensive Humanities Writing) subjects, bring together students who love to write, students who struggle with writing, students who thrive in seminar-style classes, and students who just want a chance to develop their English skills. These students prosper together and produce some remarkable work. Angles has provided them with a public outlet for that work. It also provides the CI-HW instructors with material that inspires and guides their current students. In these classes, students learn to read more critically, to address specific audiences for particular purposes, to construct effective arguments and narratives, and to use and cite source material properly. Students in these courses write a great deal; they prewrite, write, revise, and edit their work for content, clarity, tone, and grammar and receive detailed feedback from instructors and classmates. Assigned readings are related to the thematic focus of each course, and are used as demonstrations of writing techniques. The pieces in Angles may be used as teaching tools and practical examples for other students and self-learners to emulate. You can find Angles Online.

In this lesson, students will apply the use of angles to a real-world problem—finding the angle of the sun to determine the placement of solar panels. This lesson can be used to teach about angles, or to reinforce and apply understanding of angles.

This video explains how and why Fidel Castro supported the MPLA in Angola from 1975 to 2002. The Battle of Cuito Cuanavale was the largest military confrontation in Africa after World War II. The civil war in Angola was one of the longest and bloodiest conflicts of the twentieth century.

Students will learn about the Transit of Venus through reading a NASA press release and viewing a NASA eClips video that describes several ways to observe transits. Then students will study angular measurement by learning about parallax and how astronomers use this geometric effect to determine the distance to Venus during a Transit of Venus. This activity is part of the Space Math multimedia modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school textbooks. The modules cover specific math topics at multiple levels of difficulty with real-world data and use the 5E instructional sequence.

After using the historical development of concepts of conserved motion to develop introductory understanding, students are directed to a series of activities to gain a better understanding of momentum, conservation of momenta, angular momentum, and conservation of angular momenta.
Students analyze the relationship between wheel radius, linear velocity and angular velocity …
Students analyze the relationship between wheel radius, linear velocity and angular velocity by using LEGO(TM) MINDSTORMS(TM) NXT robots. Given various robots with different wheel sizes and fixed motor speeds, they predict which has the fastest linear velocity. Then student teams collect and graph data to analyze the relationships between wheel size and linear velocity and find the angular velocity of the robot given its motor speed. Students explore other ways to increase linear velocity by changing motor speeds, and discuss and evaluate the optimal wheel size and desired linear velocities on vehicles.
In uniform circular motion, angular velocity (𝒘) is a vector quantity and …
In uniform circular motion, angular velocity (𝒘) is a vector quantity and is equal to the angular displacement (Δ𝚹, a vector quantity) divided by the change in time (Δ𝐭). Speed is equal to the arc length traveled (S) divided by the change in time (Δ𝐭), which is also equal to |𝒘|R. And arc length (S) is equal to the absolute value of the angular displacement (|Δ𝚹|) times the radius (R).

In this seminar you will begin to explore the adaptations of the polar bear and learn how they stay alive in such a harsh environment. You will be thinking interdependently and using the complex reasoning skill of comparing. You will compare the adaptations of one arctic creature to another. Additionally, you will find a way to persuade people to save endangered arctic animals.StandardsStandard - 3.1.4.A5Describe common functions living things share to help them function in a specific environment.
