A triangle is made up of different positions of a second hand in a clock as shown below. The triangle formed in the given figure is called?
Right angled triangle
Isosceles triangle
From the given figure,
BC=AB (radii of the same circle)
⇒ △ ABC is an isosceles triangle.
Also, ∠ ABC= 90∘
⇒ △ ABC is a right-angles triangle.
Therefore, in the above triangle formed both the sides are equal in length and the angle between them is 90∘, so it is an isosceles right-angled triangle.
