a. since triangleABC is equilateral, write a eqaution showing a relationship betwen its angles.
b. Audrey rotated triangleABC around point A to form triangle AB'C'. She told her teammate Maria, " I think the two angles at A are equal." MAria did not know which angles she was referring to. How many angles can you find at A? Are there more than 3?
c. Maria asked Audrey to be more specific. She explained, "One of my angles is (anglesign) BAB'." at the same time, she marked her two angles with the same marking to indicate they have the same measure. Name her other angle. Be sure to use three letters so there is no confusion about which angle you mean.
a. Two angles that have a sum of 90 degrees are called complementary angles. Since angle ABD is a right angle, angles ABC and CBD are complementary. IF angle CBD= 76 degrees, what is angle ABC? Show how you got your answer.
b. Another special angle is 180 degrees . if the sum of the measures of two angles is 180 degrees, they're called supplementary angles. in the diagram, LMN is a straight angle. if angle LMP=62 degrees, what is angle PMN?
(USE THE intersecting diagram)
If x=23 degrees, find angle AEC, angle DEB, and angle CEB. show your work.
which angle is congruent to angle AED?
Angles AED and CEB are vertical angles. find another pair of vertical angles in the diagram.
