For this case we have that by definition:
A hexagon is a polygon with six sides. Thus, the figure corresponding to a hexagon is B.
The obtusangulo triangle is one that has an angle greater than 90 degrees. Thus, the corresponding figure is C.
The right triangle is one that has a rest angle, that is, an angle of 90 degrees. Thus, the corresponding figure is D.
A pentagon is a polygon with 5 sides and 5 vertices. Thus, the corresponding figure is E.
A quadrilateral is a 4-sided geometric figure. Thus, the corresponding figure is F.
Answer:
Hexagon: B
Triangle obtusangulo: C
Triangle right: D
Pentagon: E
Quadrilateral: F
