chap 10 (basic geometry)

what is a reflex angle

an angle that is bigger than 180 degrees (must state, eg: reflex angle ABC

when 2 angles add up to 90 degrees, they are called..

complementary angles (cannot use as reasoning)

when 2 angles add up to 180 degrees, they are called…

supplementary angles (cannot use as reasoning)

the sum of angles on a straight line is 180 degrees, what is the abbreviation used for reasoning angle questions with this property involved.

adjacent (angle sign)s on a straight line

when finding the value of a variable in angles, what to take note of

the variable's value should not have a degrees sign or any other units as the question wants the value of it only. (eg: x = 79 (not 79 degrees)

the sum of angles at a point is 360 degrees, what is the abbreviation used for reasoning angle questions with this property involved.

(angle sign)s at a point

vertically opposite angles are equal, what is the abbreviation used for reasoning angle questions with this property involved.

vertically opposite (angle sign)s

where to write the angle property

bracketed on the first line at the rightest side of the equation

when two parallel lines are cut by a transversal, and two angles form the 'f' property of angles, what is the abbreviation used for reasoning angle questions with this property involved.

corresponding (angle sign)s, (line name) // (line name)

when two parallel lines are cut by a transversal, and two angles form the 'c or u' property of angles, what is the abbreviation used for reasoning angle questions with this property involved.

interior (angle sign)s, (line name) // (line name)

when two parallel lines are cut by a transversal, and two angles form the 'z' property of angles, what is the abbreviation used for reasoning angle questions with this property involved.

alternate (angle sign)s, (line name) // (line name)

what to take note of when writing the abbreviation for corresponding, interior and alternate angles

comma, then the two parallel lines stated

can you add other parallel lines to a question to solve it?

yes! but it must be dotted and the letters for it must be written
