Question

ABC is a right angled triangle is which Angle A =90° and AB = AC find angle B and angle C​

Answer 1

GIVEN:-

$\large\sf{\angle{A}=90°}$

$\large\sf{AB=AC}$

$\large\sf{\angle{C}=\angle{D}}$

$\large\sf{\angle{A}=90°}$

$\large\sf{\angle{B}+\angle{C}=90°}$

$\large\sf{but,\angle{B}=\angle{C}}$

$\huge\sf\red{So,}$

$\large\sf{\angle{B}+\angle{B}=90°}$

$\large\sf{2\angle{B}=90°}$

$\large\sf{\angle{B}=\frac{90°}{2}}$

$\large\sf{\angle{B}=45°}$

$\large\sf{\angle{B}=\angle{C}=45°}$
