उत्तर


Draw RE ⊥ TS, T-E-S

ΔRTP and ΔRPS have same height RE.

`(A(ΔRTP))/(A(ΔRPS)) = (TP)/(PS)`   ...[Triangles having equal height]

`(A(ΔRTP))/(A(ΔRPS)) = 10/6`   ...[Given]

∴ `(A(ΔRTP))/(A(ΔRPS)) = 5/3`

Prove that, The areas of two triangles with the same height are in proportion to their corresponding bases. To prove this theorem start as follows:

  1. Draw two triangles, give the names of all points, and show heights.
  2. Write 'Given' and 'To prove' from the figure drawn.

If ΔABC ∼ ΔDEF, length of side AB is 9 cm and length of side DE is 12 cm, then find the ratio of their corresponding areas.


In the figure, PQ ⊥ BC, AD ⊥ BC. To find the ratio of A(ΔPQB) and A(ΔPBC), complete the following activity.


Given: PQ ⊥ BC, AD ⊥ BC

Now, A(ΔPQB)  = `1/2 xx square xx square`

A(ΔPBC)  = `1/2 xx square xx square`

Therefore, 

`(A(ΔPQB))/(A(ΔPBC)) = (1/2 xx square xx square)/(1/2 xx square xx square)`

= `square/square`
