Question

11. Construct an isosceles right-angled triangle ABC, where triangle c=90 and AC = 5 cm​

Answer 1

Given ∆ ABC where

∆c = 90°

AC = 5cm

Also , ∆ ABC is isosceles

Now in a right angle triangle ,

Hypotenuse is the largest side

So, it can't be equal to any other side

Therefore BC = AC = 6cm

Let's construct it

Step of construction

1 . Draw a line segment AC of length 5cm

2. Now ,we draw 90° frome point C

3 . Taking C as the center ,

5 cm as radius , we draw an arc

let the point where arc intersect

the ray be point B

4. Join BA , and label the sides

Thus ∆ ABC is required triangle

Thus is your Answer
