(1) in the diagram below, ac || df|| bh || and cb || fe.
find four similar triangles explain how you know they are all similar.

(2)using the simillar triangles you found in 1. complete the following extended proportion. ab/ac=de/? =? /dg=? /?

Part 1) Triangles ABC, DBG, DEF and BEH are similar

Part 2)

Step-by-step explanation:

Part 1)

we know that    

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

In this problem Triangles ABC, DBG, DEF and BEH are similar, because its corresponding angles are congruent by AA Similarity Theorem

Part 2)

Remember that

If two triangles are similar, then the ratio of its corresponding sides is equal

therefore

the answer is 14ft

step-by-step explanation:

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
