Finding angles of a triangle
In this video, we learn the skill of finding the angles of a triangle using dot products. We first find the vectors along the sides, then take their dot products. We also find the magnitudes of these vectors. Once the raw materials are ready, we divide the dot products with product of magnitudes to find cos of angles. This video also dives deep ...

Explaining The Universe on Instagram: "The Pythagorean Theorem is a fundamental principle in geometry that describes the relationship between the sides of a right-angled triangle. It states that the square of the hypotenuse—the side opposite the right angle—is equal to the sum of the squares of the other two sides. This can be written as the equation a^2 + b^2 = c^2, where a and b represent the shorter sides and c represents the hypotenuse. The theorem is used to calculate distances, design stru
