Module 1: Justifying Lines and Angles Relationship (Sophia Rizzonelli)
Form of Proofs
Form of Proof is to prove theorems involving proof
A flowchart proof should be the two-column format. You start with your statements then you give your reasoning for the AB=CD given
Proving Parallel Lines Theorems
Corresponding Angles Theorem
Same Side interior Angle theorem
Alternate Interior Angles Theorems
Alternate exterior angles
Same side exterior angle
Interior and Exterior Angles of Polygons
angle + angle = 180
Angles=180(n-2)
=180(n-2)/n
360/n> n=360/18=20
Perpendicular bisector and isosceles angle theorem
Perpendicular bisector is to intersect another line segment perpendicularly
30-60-90
45-45-90
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
