the areas of two Triangles are equal and the ratio of their bases is X:Y then the ratio of their Heights is
Answers
Answer:
The ratio of the heights of the triangles is Y : X.
Step-by-step explanation:
It is given that the area of two triangles is equal and the ratio of their bases is X : Y.
Let the two triangles are ΔABC( from which X belongs ) and ΔPQR( from which Y belongs ),
===============================
From the properties of triangle, we know : -
Area of triangle = 1 / 2 x base x height
================================
Then,
Let the bases of ΔABC and ΔPQR are base₁ and base₂ respectively, and the heights of the ΔABC and ΔPQR are height₁ and height₂ respectively.
According to the question : -
⇒ Area of ΔABC = area of ΔPQR
= > 1 / 2 x base₁ x height₁ = 1 / 2 x base₂ x height₂
= > base₁ x height₁ = base₂ x height₂
= > base₁ / base₂ = height₂ / height₁
----------------------------------
Given,
Ratio of bases is X : Y
---------------------------------
= > X / Y = height₂ / height₁
= > height₁ / height₂ = Y / X
Hence, ratio of their heights is Y : X.
