What is a a degree
👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

Wave Behavior at Boundaries
The video discusses the different ways in which waves behave when they encounter a boundary between two materials. The behavior can either be reflection, absorption, or transmission or a combination of the three. The video also explains...

What are Mutations and what are the different types of Mutations?
A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

What are adjacent angles
👉 Learn how to define angle relationships. Knowledge of the relationships between angles can help in determining the value of a given angle. The various angle relationships include: vertical angles, adjacent angles, complementary angles,...

NASA | New Craters on the Moon
Planetary scientists believe that small impacts regularly bombard the Moon, but until recently, they’ve had no way to distinguish new craters from the already pockmarked lunar surface. In 2009, NASA’s Lunar Reconnaissance Orbiter (LRO)...

What are opposite Rays
👉 Learn essential definitions of points, lines, and planes. A point defines a position in space. A line is a set of points. A line can be created by a minimum of two points. A plane is a flat surface made up of at least three points. A...
