Question

In $△ABC,AB=AC$ and AD is perpendicular to BC. State the property by which $△ADB\cong △ADC$.

• A. SAS property
• B. SSS property
• C. RHS property
• D. ASA property

Answer 1

The correct option is C RHS property

In $△ABC,AB=AC$ and $AD$ is perpendicular to $BC.$

According to the question, the triangles formed are right-angled triangles, as shown in the figure.

So, $△ADB\cong △ADC$ (R.H.S. property)
