If an angle of one triangle is congruent to the corresponding angle of another triangle and the lengths of the sides including these angles are in proportion, the triangles are similar. the remaining sets of angles will be congruent and the remaining corresponding sides will be in proportion.
Answer:
Step-by-step explanation:
given AD = DB , means D is the midpoint of AB
given AE = EC , means E is the midpoint of AC
<h3>
<u>MID POINT THEOREM</u></h3>
In a triangle ABC, if D and E is the midpoint of side AB and AC respectively.
Then DE is parallel to BC and length of DE is half of length of BC.
BC = 22 (given in the question)
Two negatives make a positive so 7*6 = 42
Answer is 42
