<- Angle

= - Congruent

m - Measurement

Given: <1 = <3; < 2 = <4

Prove <ABC = <DEF

so its like in <ABC it is bisected by D in which there is the < 1 and < 2

In < EFG it is bisected by H in which there is the < 3 and < 4

Statements:

1) < 1 = < 3 and < 2 = < 4

Reason [Given]

2) m< 1 = m< 3 ; m< 2 = m< 4

Reason [Definition of congruent]

3) m<1+m<2=m<ABC

m<3+m<4=m<DEF

WHAT IS THE REASON FOR STATEMENT 3?
