Im taking an open book open note open everything..on math and I cannot figure out this proof please help! i need it to be real correct bc my grade is depending on it! ha thanks youuu:)
1.)<axb?<cxd
2.)m<axb=m<cxd
3.)m<bxc=m<bxc
4.)m<axb+m<bxc=m<cxd+m<bxc
5.)m<axb+m<bxc=m<axc
6.)m<cxd+m<bxc=m<bxd
7.)m<axc=m<bxd
8.)axc?<bxd
The possible reasons for the proof are reflexive(rpe), definition of congruent angles(dca), addition(ape), angle addition postulate(aap) substitution(supe) and give..but number 1 is the given. please help with proofs! thank youu
