Use the image to answer the question.
An illustration shows two triangles A B C. One triangle is labeled figure A, and the other triangle is labeled figure B. For the triangle in figure A, side A C forms the base, and B is the vertex on the top. A closed circle is at the center of the triangle below the vertex B. Three lines are drawn from the circle to the vertices of A, B, and C. For the triangle in figure B, the triangle A B C has a vertical perpendicular line drawn from the middle of side A C to vertex B, dividing it into 2 smaller equal triangles inside the larger triangle. The smaller triangle on the left is labeled A, and the smaller triangle on the right is labeled B.
Select the correct decomposition of triangle ABC into triangles.
Choose 1 for Figure A , 2 for Figure B , or 3 for both Figure A and Figure B .
