In ∆ABC and ∆ADC,
∠BAC = ∠DAC | Given
∠ACB = ∠ACD | Given
AC = AC | Common
∴ ∆ABC ≅ ∆ADC | ASA Axiom
∴ AB = AD | C.P.C.T.
and CB = CD. | C.P.C.T.
AB is a line-segment. AX and BY are two equal line-segments drawn on opposite sides of line AB such that AX || BY. If AB and XY intersect each other at P. Prove that:
(i) ∆APX ≅ ∆BPY
(ii) AB and XY bisect each other at P.
Line-segment AB is parallel to another line-segment CD. O is the mid-point of AD (see figure). Show that: (i) ∆AOB ≅ ∆DOC (ii) O is also the mid-point of BC.
