Module 1: Justifying Lines and Angles Relationship (Sophia Rizzonelli)

Form of Proofs

Form of Proof is to prove theorems involving proof

Proving Parallel Lines Theorems

Corresponding Angles Theorem corresponding angles theorem

Interior and Exterior Angles of Polygons

Same Side interior Angle theorem same side interior angles

A flowchart proof should be the two-column format. You start with your statements then you give your reasoning for the AB=CD given

Alternate Interior Angles Theorems alternate interior

Alternate exterior angles exterior

angle + angle = 180

Perpendicular bisector and isosceles angle theorem

Perpendicular bisector is to intersect another line segment perpendicularly

30-60-90 triangle11

45-45-90 triangle11

Angle relationships inside and outside circle

Inscribed angle theorem = m angle MPT=1/2(m * arcMT)

Interior angle of a circle theorem 1/2(arc 1+ arc 2)

Exterior of circle theorem= m angle EJT=1/2(m* arcET-m arcRT

Angles=180(n-2)

=180(n-2)/n

360/n> n=360/18=20
