TRUE OR FALSE: vertical angles also form several supplementary angles.
TRUE
In quadrilateral ABCD, angle A is 70 degrees, angle B is 65 degrees, angle C is 110 degrees, how many degrees is angle D?
115 degrees
Angles that are congruent and opposite of each other that are formed by the intersection of two lines are called what?
Vertical Angles
True or false. If <A measures 27 degrees and <B measure 73 degrees, these two angles will form a complimentary angle.
FALSE
If angles G and F are supplementary. Find the value of each ANGLE if m<G is 2x and the m<F is 2x-4.
HINT: you must solve for x then plug it back in to find the angle.
