2. As shown in the figure, ab = AC, MB = MC, is the straight line am the vertical bisector of BC?

2. As shown in the figure, ab = AC, MB = MC, is the straight line am the vertical bisector of BC?


Because AB = AC, point a is on the vertical bisector of BC. Similarly, point m is on the vertical bisector of BC. Then a straight line is determined according to the two points. It can be seen that am is the vertical bisector of BC



As shown in the figure, ab = AC, MB = MC, prove that the straight line am is the vertical bisector of the segment BC


Because AB = AC, Ao is the vertical bisector of BC
Because MB = MC, Mo is the vertical bisector of BC
Because of (1) and (2), the line am is the vertical bisector of segment BC



AB = AC, MB = MC. Prove: Line am is the vertical bisector of line BC


It is proved that: ∵ AB = AC, ∵ point a is on the vertical bisector of BC, ∵ BM = cm, ∵ point m is on the vertical bisector of BC, ∵ line am is the vertical bisector of BC



AB = AC, MB = MC. Prove: Line am is the vertical bisector of line BC


It is proved that: ∵ AB = AC, ∵ point a is on the vertical bisector of BC, ∵ BM = cm, ∵ point m is on the vertical bisector of BC, ∵ line am is the vertical bisector of BC
