11.The ratio of the areas of two similar triangles ABC and PQR is 25:144.What is the ratio of their medians?
Answers
Answer:
Ratio of the two similar triangles is 25:144
Step-by-step explanation:
AB²/PQ²=25/144
AB/PQ=√25/144
AB/PQ=5/12
Ratio of their medians is 5:12
Given : The ratio of the areas of two similar triangles ABC and PQR is 25:144.
To Find : Ratio of their medians?
Solution:
For Similar triangle Ratio of corresponding sides is Equal and corresponding angles are equal.
ΔABC ~ ΔPQR
Ratio of Area of similar triangle = ( Ratio of corresponding sides)²
=> 25/144 = ( Ratio of corresponding side)²
=> (5/12)² = ( Ratio of corresponding side)²
=> Ratio of corresponding side = 5/12
In similar triangles
Ratio of corresponding Medians =Ratio of corresponding side
=> Ratio of corresponding Medians = 5/12
ratio of their medians = 5 :12
