Answer 1

Answer:

Answer 2

Answer:

Given: <A = 90

= AB = AC (Given)

To Prove: <B = <C

=> Additional Construction: Draw a AD bisector of <A and BC

Proof: ΔADB and ΔADC

= AD = AD (Common Side)

= <DAB = <DAC (AD is the bisector of <A)

= AB = AC (Given)

∴ By SAS Congruence rule,

= ΔDAB ≅ ΔDAC (CPCT)

∴ <B = <C (CPCT)
