How many different triangles can be constructed with three angles, each measuring 60°? one , more than one or none

A protractor would help and think about it as how many 60 degrees could go into all or most triangles. This would help you out a lot!

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c

If you divide 0.1 and 0.6 you wii get 0.166666 which rounds to .167 which is answer b
