Question

find the perimeter of isosceles right angled triangle where each of congruent side is 10cm​

Answer 1

Answer:

: Find the area and perimeter of an isosceles right triangle whose hypotenuse side is 10 cm. Therefore, the length of the congruent legs is 5√2 cm. Therefore, the perimeter of an isosceles right triangle is 24.14 cm.

Answer 2

Answer:-

Let the other side of triangle is x cm

Then in isosceles right angled triangle each of congruent side is 10 cm

x² = (10)² + (10)²

⇒x² = 100 + 100

⇒x² = 200

⇒x = √200

⇒x = 10√2

Then perimeter of right angled isosceles triangle

⇒10 + 10 + 10√2

⇒20 + 10√2

⇒10√2 + (√2+1)
