In ΔABC, AB = BC = K, AC = $$\sqrt 2 $$ k, then ΔABC is a :
A. Right isosceles triangle
B. Isosceles triangle
C. Right-angled triangle
D. Equilateral triangle
Answer: Option A
Solution(By Examveda Team)
∵ AB = BC = K
⇒ AC = $$\sqrt 2 $$ K
⇒ (AC)2 = (AB)2 + (BC)2
⇒ ($$\sqrt 2 $$ K)2 = K2 + K2
⇒ 2K2 = 2K2
⇒ Therefore ΔABC will be a right isosceles triangle.
