Construct a segment of a circle on a chord of length 5cm. containing the following angles.
90°
Answer :
Given an angle of 90° and chord 5cm
Steps of construction:
Rough image:
Explanation:
x + x + 90° = 180°
[using sum of all angles in a triangle = 180°]
⇒ 2x + 90° = 180°
⇒ 2x = 180° - 90°
⇒ 2x = 900°
⇒ x = 
= 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 centre ‘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.
