Question

- In the figure, find the measure of angles.
1, 2, 3, 4. Find the sum of 1, 2 and 3
What is the relation between the sum of the
interior angles and the sum of exterior angles.​

Answer 1

Step-by-step explanation:

Angle 1 be x:

80+X=180

x=180-80=100° { linear pair}

Angle 3 be y:

60+y=180y=180-60=120° { linear pair}

Angle 4 be z:

60+80+z=180. { Angle Sum Property of Triangle , sum all angles is 180}

60+80+z=180

140+z=180

z=180-140= 40°

Angle 2= Sum of opposite interior angles of triangle

Angle 2= 80+60= 140°

The sum of Angle 1+2+3= 100+120+140=360°{ sum of all exterior angle of triangle or any other polygon is 360°}
