Explanation:

x+x+90=180

[using sum of all angles in a triangle =180]

2x+90=180

2x=18090

2x=90

x=902=45

Step 1: Draw a line segment AB=5cm

Step 2: Draw an angle of 45 on point A and B to intersect at O.

Step 3: With center "O" and radius OA and OB, draw the circle.

Step 4: Mark a point 'C' on the arc of the circle. Join AC and BC.

we get CAB=90

Thus, ACB is the required circle segment.
