Question
Draw seg AB = 6.8 cm. Draw a circle with diameter AB. Draw point C on the circle apart from A and B. Draw line AC and line CB. Write the measure of angle ACB
Solution
Analysis:
seg AB is the diameter of the circle and the midpoint of seg AB is the centre of the circle. So we draw a perpendicular bisector of seg AB in order to find the centre of the circle.
Step of Construction:
- Draw seg AB of length 6.8 cm
- Draw perpendicular bisector of AB. It intersects AB in point O.
- With O as centre and radius equal to AO, draw a circle.
- Take any point C on the circle and draw seg AC and seg CB.
- Find m∠ACB.
Measures of ∠ACB = 90°
