### Question Asked by a Student from EXXAMM.com Team

** Q 1780156017. ** Suppose chords `AB` and `CD` of a circle intersect at

a point `P` inside the circle. Two right angled

`DeltaA' P' B'` and `DeltaD.C'Q' D'` are formed as shown in the

figures below such that `A' P' = AP, B' P' BP,

C'Q' = CP, D'Q' DP` and :`A' P' B' = 90^0`

`=angleC'Q'D'`.

Which of the following statements are not

correct?

1. `DeltaA' P' B'` and `DeltaC' Q D'` are similar triangles but need

not he congruent.

2. `DeltaA'P' B'` and `DeltaC' Q' D'`are congruent triangles.

3.`DeltaA' P'B'` and `DeltaC'Q' D'`arc triangles of same area.

4. `DeltaA' P' B'` and `Delta.C' Q' D'` are triangles of same

perimeter.
