4.3 Similar Triangles

(Read page 146 to 149)

Proportional - in a shape it means same shape but different size

Corresponding - a comparison of two similar sides or angles in an object





Corresponding: LA ~ LD
LB ~ LE
LC ~ LF


LA = LBAC = LCAB LD = LEDF = LFDE
LB = LABC = LCBA LE = LDEF = LFED
LC = LACB = LBCA LF = LEFD = LDFE






Corresponding angles will ALWAYS be equal

The vertices are always upper case
Sides are always lower case






Example 2 ( Question 2 )







Homework
