Law of Sines
This is the Law of Sines
What is a/sin(A)=b/sin(B)=c/sin(C)
This is the Law of Cosines
What is a2+b2-2abcos(C)=c2
Both the law of sines and cosines used for this
What is finding missing angles and sides?
The placement of lowercase letters is associated with this part of triangles
What are the sides of the triangle?
Upper case letters in formulas for the Laws of Sines and Cosines are used to represent these
What are angles of the triangle?
The sum of the angles of any triangle must be this number
What is 180 degrees?
The function used when finding an angle measure in law of sines
What is the inverse sine function
Solve for the side c of a triangle if a=10, b=13, and the measure of angle C=27 degrees
6.11 units
No triangle can have two of these angles.
What are angles greater than or equal to 90 degrees (will accept obtuse angles)
The solution for side b=?, when B=78', A=58', and a=33
What is 38
This is what the formula for the Law of Cosines looks like after solving for cos(C)
cos(C)=(a2+b2-c2)/2ab
The congruence postulates for non-right triangles are AAS, SSS, SAS, and this postulate
What is ASA?
What is the range of the Sine function?
Range is from -1 to 1
