Question

Triangle ABC is an equilateral triangle
what are the degree measures of angle 1,2,3,4 and 5

Answer 1

Answer:

Answer: For an equilateral triangle, all angles are the same. Therefore, all the angles are 60°.

Answer 2

Given : Equilateral Triangle

To Find : degree measures of angle 1,2,3,4 and 5

Solution:

angle 1 is angle of Equilateral  triangle

Hence m∠1  = 60°

Red triangle is Equilateral

Hence angle adjacent to opposite of ∠2 is 60°

=> angle  opposite of ∠2 = 180° - 60° = 120°

As its a parallelogram hence  angle  opposite of ∠2  =  ∠2

=> m∠2  = 120°

m∠5  = 120°    ( 180° - 60°) or angle of Hexagon

Similarly

m∠3  = 60°  

m∠4  = 120°
