Question

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?

• A. Scalene triangle
• B. Right angled triangle
• C. Isosceles triangle
• D. Both B and C

Answer 1

Answer: (B), (C)

The correct options are
B

Right angled triangle

C

Isosceles triangle

From the given figure,

BC=AB (radii of the same circle)

$\Rightarrow$ $△$ ABC is an isosceles triangle.

Also, $\angle$ ABC= ${90}^{\circ }$

$\Rightarrow$ $△$ 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 ${90}^{\circ }$, so it is an isosceles right-angled triangle.
