A guide 
 How
to find the exact value of sin/cos/tan of
0, 30, 45, 90, 120, 135, 150, 180, 210, 225,
240, 270, 300, 315, 330, 360 using the unit
circle and SRT’s.
 Similarity theorem – use AA, SAS, SSS to
determine whether triangles are similar and
draw conclusions based on that similarity
 Derive the area formulas – parallelogram,
triangle, quad with perp diagonals, trapezoid
 Use inscribed angles and similarity to explain
why a theorem is true (circles)
 Quadrilateral theorems (must explain 2)
Solve a right triangle (trig, Pythag)
 Find the area of a quadrilateral – must use 3060-90 to find missing side before calculating area
 Use circle theorems to show triangles are similar
– calculate area of similar figures

Write proportions to solve for side lengths
 Use that ratio of areas = (ratio sides)^2

Calculate the area of a sector
 Find the volume and surface area of a solid (you
will get a formula sheet)
 Find the area of a regular hexagon
 Area of circle

 Midsegment
 Sine,
cosine, tangent
 Unit circle
 Area postulates – 1, 2, 3
 Midquad
 Rhombus/llogram (know difference between
definitions and theorems)
 Secant segments
 Inscribed angles ½ arc
 Tangent segments perp to radii
 AA
similarity
 Side splitter v/s similar triangles
 Pythagorean theorems
 Height v/s slant height – find one using the
other
