KS3_Angles and lines

Angles on around a single point add up to 360 degrees

• True
• False

angle x = 37 degree because both angles are:

• Alternate angles

• Parallel angles

• Vertically opposite angles

• Corresponding angles

Angles on a straight line add up to 360 degrees

• True
• False

Angles b equals

• 140 degrees as it's an alternate angle

• 220 degrees because angles around a point add to 360

• 40 degrees because it's vertically opposite

• 40 degrees because angles on a straight line add to 180 degrees

This shape is a regular pentagon because it has 5 sides that are equal and 5 angles that are also equal

• True
• False

Angles b and d are

• Equal because they are on a straight line

• Dangerous angles

• Equal because they are vertically opposite

• Alternate angles and hence equal

Each exterior angle of this shape should be

• 90

• 60

• 72

• 108

Each Interior angle of this shape should be

• 90

• 60

• 72

• 108

Those two angles in the picture are called

• Corresponding angles and are equal

• Corresponding angles and they add to 180 degrees

• Co-interior angles and they are equal

• Co-interior angles and they add to 180 degrees

If each interior angle of this equilateral triangle is equal to (3a) the value of a should be

• 60 degrees

• 20 degrees

• 30 degrees

• None of these answers. Mr Shahin is trying to trick us
