Question

In a concave quadrilateral, let the two line segments joining the opposite vertices be represented by d₁ and d₂, then


both d₁ and d₂ lie in its interior

both d₁ and d₂ lie in its exterior

some part of d₁, d₂ lies in the interior and some of it in the exterior

one of d₁ and d₂ lies in interior and other in exterior​

Answer 1

Concave quadrilateral: A quadrilateral is called a concave quadrilateral, if at least one line segment joining the vertices is not a part of the same region of the quadrilateral. That is, any line segment that joins two interior points goes outside the figure.

Answer 2

Step-by-step explanation:

• some part of d₁, d₂ lies in the interior and some of it in the exterior

• one of d₁ and d₂ lies in interior and other in exterior
