Question

Which criterion for congruency of triangles makes $△$ABC and $△$ADC congruent?

• A. SAS
• B. ASA
• C. SSS
• D. RHS

Answer 1

The correct option is D RHS

In $△ABC$ and $△ADC,$
$\angle B=\angle D={90}^{\circ }.$ .....(given)
AB = AD ..... (given)
AC = AC ...... (common hypotenuse)
$\therefore$ $△ABC\cong △ADC$ ...... (RHS criterion)
