\huge \sf \color{Blue}\underline{\underline{Question}}

ABC is right ANGLED triangle in which ∠A=90 , AB=AC FIND ∠B and ∠C .

\huge \sf \color{Blue}\underline{\underline{Answer :}}

∠B =∠C = 45°

\huge \sf \color{Blue}\underline{\underline{Solution :}}

\large \sf \color{Green}\underline{\underline{Given:}}

∠A= 90°

AC=AB

Hence, ∠B =∠C ( Opposite side are EQUAL)

we know that ,

\sf \color{red} \sf{\boxed{Sum\ of \ 3\ sides \ of \triangle =180°}}

∠A+∠B+∠C =180°

∠B =∠C ( Opposite side are equal)(AC=AB)

➩∠A+∠B+∠B =180° (∠B =∠C )

➩90° + 2∠B =180°

➩2∠B= 90°

➩∠B = 45°

∠C = 45° ( ∠B =∠C )
