Given two similar triangles http://tdsb.elearningontario.ca/cont...s/triangle.gifABChttp://tdsb.elearningontario.ca/cont.../wigleqils.gifhttp://tdsb.elearningontario.ca/cont...s/triangle.gif and DEF, determine the measurement of the unknown sides.

AB = 8cm

DF = 10cm

http://tdsb.elearningontario.ca/cont...ages/angle.gifA = http://tdsb.elearningontario.ca/cont...ages/angle.gifD = 60°

AC = 12cm

EF = 9cm

How should I draw a triangle of ABC and DEF from these values ? If AB and DF, how can I get ABC ? And what unknown sides ? Im confused :S

Another question I have:

2 sides of one triangle are in proportion to 2 sides of a second triangle. One angle - not the contained angle - is equal to another angle - not the contained angle - in the second triangle.

Is this a similar triangle ? If not why.
