Geometry Concepts for review

G.1 a,b,c  LOGIC

  Students use deductive reasoning to construct and judge the validity of a logical argument consisting of a set of premises and a conclusion. This will include:

 a) identifying the converse, inverse, and contrapositive of a conditional statement 

b) translating a short verbal argument into symbolic form

 c) determining the validity of a logical argument

Please review this material with the following material:
.  Use chain reasoning to make a logical conclusion given a set of statements.

Section 2.2 Reasoning and Direct Proofs

p. 70 Inductive Reasoning,

p. 71 Counterexample,

p. 72 Deductive Reasoning

Please work these examples and check them against my key which you may request- feel free to work together - using social distancing of course!

Remember you may access the video section of the book to reinforce your knowledge

G.4 construct and justify the construction of
 a) line segment congruent to a given line segment
b) the perpendicular bisector of a line segment
e) the bisector of a given angle
 f) an angle congruent to a given angle
G.12 solve problems involving equations of circles.

Unit 3 Angle relationships with Intersecting and Parallel lines

G.2 Use the relationships between angles formed by two lines intersected by a transversal to: 

 a) prove two or more lines are parallel

b) solve problems, including practical problems, involving angles formed when parallel lines are intersected by a transversal

 G.4 construct and justify constructions of:
c) a perpendicular to a given line from a point not on the line

d) a perpendicular to a given line at a given point on the line

 g) a line parallel to a given line through a point not on the line
