Perpendicular bisector

MX is a line coming from the center and bisects the line AB at a right angle. What do you know about lines AX and XB?

• They are the same

• AX is bigger

• XB is bigger

• None of these answers

If XB=35cm what is the value of AX?

• 50cm

• 35cm

• 17.5cm

• 70cm

In the diagram, the diameter of the circle is perpendicular to the chord. Solve for the value of "x"

• 26
• 24
• 30
• 20

Solve for x

• 6
• 7
• 8
• 9

If the circle's center is at M what is the value of the angle created at both E and D? (hint they are the same)

• 90 degrees

• right angles

• 90 degrees but in yellow

*hint: use angles in a 4 sided shape are equal to 360 degrees

Use the previous answer to work out the angle EMD (the angle at M).

• 33 degrees

• 90 degrees

• 147 degrees

• 57 degrees
