Step-by-step explanation:
Given 1hal ABCO 1s a rec1ang1e.
Now.DC • AB • 24 cm (Opposesldesolte<:!Mgleare equal)
Now. each engleof rectangleISangNangle.
So, LA = LB • LC = LD = 90•
Now, LOSA + LABC • 180° (Linear pa11)
•LOSA • 90'
In LIOBA
Acr' = Ae2 + OB' (Pylrlago<as lhe«em)
-Acr s 24' + 71 • 576 + 49 = 625
•AO = 25 cm
Now, AO • BC • 9 cm
Nmv, P rs the mid pornIof DC, then
OP = PC • 12cm
ln llOCP
Pa2 = oc> + PC' (Pythagoras theorem)
=162 + 122
= 256+ 144
= 400
-PO = 20an
In LIAOP,
AP' = Ao' + OP'
=92 + 122
=81 + 144
=225
So,AP = 15cm In LiAPQ,
AQ2 = 252 = 625
AP' + P02 = 152 + 202 = 225 + 400 = 625
Since, AP' + P02 = Acl-
So,by converse of Py1hagoras theorem, LAPO = 90°
