Question

Three unit vectors A, B and Ĉ are arranged in a closed figure such that A+B=Ĉ. The figure will be
O Right angled triangle
O An equilateral triangle
Isosceles triangle
O All of these
&​

Answer 1

Answer:

It would be a Right angled triangle.

Answer 2

The correct answer is option (a.) Right angled triangle.

Explanation:

• A right triangle or right-angled triangle, or more formally an orthogonal triangle, is a triangle in which one angle is a right angle.
• The relation between the sides and other angles of the right triangle is the basis for trigonometry.
• Three unit vectors A, B and Ĉ are arranged in a closed figure such that A+B=Ĉ. The figure will be Right angled triangle.
• Prove by vector method that in a right angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
