What reason would you use to calculate that b = 72
angles in a triangle add to 180
angles at a point add to 360
vertically opposite angles are equal
angles on a straight line add to 180
this diagram has which type of angles marked?
vertically opposite angles
angles at a point
angles on a straight line
angles in a triangle
describe this pair of marked angles
alternate angles on parallel lines
co-interior angles on parallel lines
corresponding angles on parallel lines
The correct name for a pair of F angles is angles on lines
A and ❌ are angles on a straight line. B and C are ❌ angles. ❌ and G are corresponding angles on parallel lines. Another pair of corresponding angles is ❌ and B. There are two pairs of co-interior angles - C and ❌ as well as ❌ and F C and F are ❌ angles on parallel lines as are D and E.
Angles on a straight line add to 360 degrees
