I wonder that the solve rate for the triangle problem would be if you gave it to students while teaching them similar triangles vs. law of sines.

ReplyDeleteI don't yet see how to solve it either way. (I'm working with my students right now on Law of Sines, so if it's a reasonable problem, I can give it as a challenge.)

ReplyDeleteWhenever a problem says angle A = angle B, that sets off my "similar triangles" flag.

DeleteOne might even call it "AAAdar". ;)

hee hee. Yeah, I didn't slow down enough. Once I drew it out carefully, it became super simple. Trust, that's what it took. Thanks.

DeleteSue, the Numberplay link actually goes back to Five Triangles; need correction... as far as contacting Five Triangles perhaps tweet them @Five_Triangles and see if they respond

ReplyDeleteThanks. I saw that all the links opened wrong, so I fixed that too. (I like to have them open in a new window.)
