a, XétABM vàECM có:
\(MA=ME\) ( gt)
\(\hat{AMB}=\hat{CME}\) ( đối đỉnh)
\(\) \(MB=MC\) ( AM là đường trung tuyến)
Do đó:ABM=ECM (c-g-c)
Suy ra `AB=CE`(2 cạnh tương ứng)
\(\hat{BAM}=\hat{MEC}\) ( 2 góc tương ứng)
b, VìABC vuông tại B nên:
`=>` `AC > AB`
`=>` `AC > CE`
`=>` \(\hat{MEC}>\hat{MAC}\)
Suy ra \(\hat{MAB}>\hat{MAC}\)
