@Directrix did i fix it?

Answer 8

ok so you just use the AA theorem. No not the alcoholics anonymous theorem. AA stands for angle angle. the middle angles near M are equal so you have 2 pairs of angles (each congruent). the aa theorem will let you prove the triangles are congruent. so it's as easy as that. I just learned this the other day.

Answer 9

@mathrockz1 I see one pair of congruent angles in the diagram. The AA postulate for triangle similarity requires two pairs. Where is the second pair?

Answer 10

near M

Answer 11

here ill draw it or try to
