Ex 7.1 || Q 3,4,5 || distance formula, midpoints || Math 9th new book

The video explains how to calculate the distance and midpoint between two given points, as well as how to determine if points form a right-angle triangle, isosceles triangle, or parallelogram using distance formulas. The video covers the following: Calculating distance and midpoint (0:02): Learn how to use the distance formula to find the distance between two points and the midpoint formula to find their midpoint. Identifying points at a specific distance from the origin (7:27): The presenter shows how to determine which points are exactly 15 units away from the origin (0,0) by applying the distance formula. Verifying right-angle triangles (10:14): Understand how to use the Pythagorean theorem to prove if three given points form a right-angle triangle. Identifying isosceles triangles (14:59): The video demonstrates how to check if a triangle is isosceles by calculating the lengths of its sides and verifying if two sides are equal.
