A small exhaust fan with a diameter 7cm is to be fitted at the centre of a 9cm by 9cm square metal panel i. Accurately draw the 9cm by 9cm square

ii. Accurately draw the diagonals to locate the centre of the square panel and the centre circle

iii accurately draw the circle

go and ask your mom to you

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.

126 maybe. sorry
