Question

In adjacent figure AD || BC and AD = BC
(i) Is ACAD=ABCA, give reason.
(ii) Find angle D.
(iii) Is AB ||CD?
✨ Please answer briefly ✨ ​

Answer 1

Step-by-step explanation:

In triangle bac and triangle adc, we have

AD = BC (GIVEN)

ABCA = AADC (CORRESPONDIND ANGLE)

AC = AC (COMMON)

TRIANGLE BAC AND TRIANGLE ADC IS CONGRUENT BY SAS CRITERIA

THEREFORE, ACAD = ABCA BY CPCT
