Right-angled triangle using coordinates

निर्देशांकों द्वारा समकोण त्रिभुज

In this Class 9 Mathematics topic from Coordinate Geometry, students learn how to represent the vertices of a triangle as ordered pairs and plot them on the Cartesian plane. They examine the positions and coordinate differences of the points to identify when two sides are perpendicular and the triangle is right-angled. The topic develops accuracy in plotting, reading coordinates, comparing horizontal and vertical changes, and explaining geometric relationships using a diagram and clear mathematical reasoning.
