Question

Which of the following shapes may or may not have a right angle?

• A. Square
  
• B. Rectangle
  
• C. Trapezoid
  
• D. Right triangle
  

Answer 1

The correct option is C Trapezoid


Option A
Right triangle: It is a triangle which has one right angle, and hence it is called a right triangle.
Option B
Trapezoid: A trapezoid has only one pair of parallel opposite sides, and if it has one angle equal to ${90}^{\circ }$, then it is called a right trapezoid.
Therefore, a trapezoid is the only shape among the given options that may not always have a right angle.
Option C
Rectangle: A rectangle has all four angles equal to ${90}^{\circ }$ and opposite sides parallel and equal.
Option D
Square: A square has all four angles equal to ${90}^{\circ }$ and all sides equal.
Hence, the trapezoid is the only shape that may or may not have a right angle.
