Use Euclid’s division lemma to show that the square of any positive integer is either of the form 3m or 3m + 1 for some integer m. Solutions: Let x be any positive integer and y = 3. By Euclid’s division algorithm, then, x = 3q + r for some integer q≥0 and r = 0, 1, 2, as r ≥ 0 and r < 3. Therefore, x = 3q, 3q+1 and 3q+2

Web4. If the areas of two similar triangles are equal, prove that they are congruent. Solution: Say, ΔABC and ΔPQR are two similar triangles and equal in area. Now, let us prove ΔABC ≅ ΔPQR ΔABC ~ ΔPQR ∴ Area of (ΔABC)/Area of (ΔPQR) = BC 2 /QR 2 ⇒ BC 2 /QR 2 =1 [Since, Area (ΔABC) = (ΔPQR) ⇒ BC 2 /QR 2 ⇒ BC = QR Similarly, we can prove that mysticaria minecraft seed
