Question

ABC is an isosceles triangle rights angled at C. Prove that AB2 =2AC2. ​

Answer 1

Answer:

since the triangle is isosceles and right angled at C

AC = BC

now

by Pythagoras theorem

Hypotenuse² = base²+perpendicular ²

AB² = BC² + AC²

AB² = AC² + AC² ( AC = BC)

AB² = 2AC²

Step-by-step explanation:

hence proved!!!!
