This is what i have so far: ( I would appreciate if you could tell me if it is wrong or right!) a. m<1 = m<2 : given b. <1 is supplementary to <2. : Definition of supplementary angle c. m<1 + m<2 = 180degrees :Linear pair postulate d. m<1 + m<1 = 180degrees 2(m<1) = 180degrees : (this is one step. but the 2(m<1) = 180degrees is right below the first one

PDF Pre-AP Geometry Section 2.7 Homework turn in project Proof – Given: m 1 + m 2 = m 4 Prove: m 3 + m 1 + m 2 = 180° Paragraph Proof: It is given that m 1 + m 2 = m 4. 3 and 4 are supplementary by the Linear Pair Theorem. So m 3 + m 4 = 180° by definition. By Substitution, m 3 + m 1 + m 2 = 180°. Statements Reasons 1. m 1 + m 2 = m 4 1. Given 2. 3 and 4 are supp. 2.102 Chapter 2 Reasoning and Proofs Writing a Two-Column Proof Prove this property of midpoints: If you know that M is the midpoint of AB — , prove that AB is two times AM and AM is one-half AB.
