Question

if sinA=cosA prove that angle A= angle C​

Answer 1

Answer:

Let me help ⬇️⬇️

Step-by-step explanation:

Since sin a =Cos A therefore p /h=b/ h

➡️ p=b

➡️ Angle opposite perpendicular =angle opposite base (since angle opposite to equal sides are equal)

Since perpendicular is BC and base is AB for angle A therefore BC =AB

➡️ Angle A = angle C . Hence proved
