What are all the types of angles that can be congruent to each other ?
@nincompoop
may i help you?
please.
okay
do you know what are all the types of angles that can be congruent to each other ?
yes
enlighten me c:
lets start frist is acute angle =an angle whose measure is less then 90 degress |dw:1431800723780:dw|
ok.
i wrote down VERTICAL ANGLES too.
Obtuse angle: An angle whose measure is bigger than 90 degrees but less than 180 degrees. Thus, it is between 90 degrees and 180 degrees. The following is an obtuse angle. http://prntscr.com/75xkws
|dw:1431800825968:dw|
so all types?
no
|dw:1431800863083:dw|
ok

adjacent then?
Angles 3,4,5,8 are interior angles Angles 1,2,6,7 are exterior angles Alternate interior angles: Pairs of interior angles on opposite sides of the transversal. For instance, angle 3 and angle 5 are alternate interior angles. Angle 4 and angle 8 are also alternate interior angles. Alternate exterior angles: Pairs of exterior angles on opposite sides of the transversal. Angle 2 and angle 7 are alternate exterior angles. Corresponding angles: Pairs of angles that are in similar positions. Angle 3 and angle 2 are corresponding angles. Angle 5 and angle 7 are corresponding angles
Which are congruent then? o_o
