Congruent Angles and Vertical Angles.
Congruent Angles are two or more angles with the same measure.
Vertical Angles are two non-adjacent angles formed by two intersecting lines. Vertical angles are congruent.
Examples:
AR
А B
3
DA
21 and 23 are vertical angles
ZAOB are DOC vertical angles
22 and 24 are vertical angles
ZBOC and LAOD are vertical angles
Use your protractor to measure each angle in the figure
Find:
mZ1 =
m2 =
m 23=
m 4 =
m ZAOB =
m BOC =
m 2DOC =
m AOD =

Answer:
congruent angles and vertical angles.
congruent angles are two and more angles with the same measure.vertical angles are two non-adjacent angles formed by two interesting lines.vertical angels are congruent .
example:A R A B 3 DA 21 are vertical angles ZAOB DOC vertical angles 22 and 24 are vertical angles use your protractor to measure each angle in the figure find:MZ1=M23=M4=M AOB=M BOC=M DOC=M AOD
