Question

Show that the points (0, 7, ‒10), (1, 6, ‒6) and (4, 9, ‒6) are the vertices of an isosceles triangle.​

Answer 1

Answer:

Step-by-step explanation:

Let P (0, 7, 10), Q (–1, 6, 6) and R (– 4, 9, 6) be the given three points. Here Now PQ2 + QR2 = (3√2 )2 +(3√2 )2= 18 + 18 = 36 = (PR)2 Therefore, Δ PQR is a right angled triangle at Q. Also PQ = QR. Hence Δ PQR is an isosceles triangle.Read more on Sarthaks.com - https://www.sarthaks.com/121632/show-that-the-points-0-7-10-1-6-6-and-4-9-6-form-a-right-angled-isosceles-triangle
