Question

if l||m angle 1 is 60 degree angle to is 120 degree angle is 120 degree find the measure of each of the remaining angles​

Answer 1

Answer:

A1=60°. .. GIVEN

A2=120°. .. GIVEN

A2+A3=180°. .. LINEAR PAIR

120+A3=180

A3=180 - 120

A3=60

A3+A4=180°. ... LINEAR PAIR

60+A4=180.

A4=180-60

A4=120°

INSTEAD OF THIS YOU CAN MEASURE THE DEGREE OF A4 LIKE THIS

A2=A4. .. VERTICALLY OPPOSITE ANGLES

THEREFORE. 120= 120

A2=A6. .... CORRESPONDING ANGLES

120=120

A6=A8. ... VERTICALLY OPPOSITE ANGLES

120=120

A3=A7. .... CORRESPONDING ANGLES

60=60

A7=A5. ... VERTICALLY OPPOSITE ANGLES

60=60
