Which statement about this figure is true. I It has no reflectional symmetry. 2 It has point symmetry. 3 It has reflectional symmetry in a plane. 4 It has rotational symmetry with an angle of rotation of 120 degrees

32

step-by-step explanation:

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
