Answer:
Figure A
Step-by-step explanation:
We are given that a statement
''If is is an triangle , then it has three vertices.
We have to find that which diagram represents the given statement
From first diagram
If triangle then it have three vertices because intersection of triangle and three vertices is triangle.
From second diagram
Intersection region of three vertices and triangle is three vertices.
So, from second diagram we cannot say if a triangle then it has three vertices.
Hence, figure A represent the given statement.
