Don't let all the words and the picture mess you up...just find the midpoint of BC!

rise over run....find a place where the graph hits an intersecting grid....walk up and over to find another location. the up is the top and the over is the bottom of your fraction

#sides=360/ext angle
find the ext angle (180-int angle)
then use the formula to find the #sides.

x is an exterior angle so...
ext angle=360/#sides

(1) find the sum of the interior angles of a quadrilateral (sum = (#sides - 2)*180)
(2) add everybody up and set equal to the sum you found in the first step

assume this is sitting inside a circle, count the number of sections, then do 360/#sections

(SSS) If 3 sides of one triangle are congruent to 3 sides of another triangle, then the triangles are congruent.
(SAS) If 2 sides and the angle between them in one triangle are congruent to 2 sides and the angle between them in another triangle, then the triangles are congruent.
(ASA) If 2 angles and the side between them of one triangle are congruent to 2 angles and the side between them of another triangle, then the triangles are congruent.
(AAS) If 2 angles and a side not between them are congruent to 2 angles and a side not between them of another triangle, then the triangles are congruent.
