Title: Class 10 Maths Ex 7.1 Q3 & Q4 | Coordinate Geometry (NCERT) - Collinear & Isosceles Check

---
*Description:*
*Struggling with the Distance Formula?* This video provides the complete, easy-to-follow solutions for two essential problems from **Class 10 Maths NCERT, Chapter 7, Exercise 7.1 (Coordinate Geometry)**.

We break down the calculations step-by-step:

1. Are the Points Collinear? (Question 3) 📐
We check if points (1, 5), (2, 3), and (-2, -11) lie on the same straight line. We use the *Distance Formula* three times and test the condition for collinearity.

2. Identifying an Isosceles Triangle (Question 4) 🔺
See how to prove that the points (5, -2), (6, 4), and (7, -2) form an **isosceles triangle**. The key is showing that two of the calculated side lengths are equal!

*In this video, you will learn to:*
Accurately apply the Distance Formula.
Test for collinearity of points.
Identify the type of triangle formed by three given vertices.
