Question

Assertion (A) : AABC is an isosceles triangle right angled at C, then AB2 =2AC2 Reason (R) : In AABC, right angles at B, AC2=AB2+BC2.​

Answer 1

Answer:

in triangle ∆ABC,

Step-by-step explanation:

by pythagoras theorem

• (Ab)²=(Ac)²+(Bc)²
• since ∆ABC is isosceles triangle
• Ac=Bc
• (AB)²=2(Ac)² {hence proved}
