Question

If ∠A and ∠P are acute angles such that tan A = tan P, then show that ∠A = ∠P.

Solution

A and P are acute angle tan A = tan P

Let us consider right angled triangle ACP,

We know `tan theta = "opposite side"/"adjacent side"`

`tan A = (PC)/(AC)`

`tan A = (AC)/(PC)`

`tan A = (AC)/(PC)`

tan =tan P

`(DC)/(AC) = (AC)/(PC)`

`(PC)^2 = (AC)^2`

𝑃𝐶 = 𝐴𝐶   [∵ Angle opposite to equal sides are equal]

∠𝑃 = ∠𝐴

  Is there an error in this question or solution?
