Answer:
A = 120
Step-by-step explanation:
Angle A is a vertical angle to 120 and vertical angles are equal
A = 120
Answers:
- a) No, the figure would not look the same. See the diagram below
- b) Yes the figure would look the same after a half turn
- c) Yes the figure would look the same after a full turn
==================================================
Explanations:
- a) The figure doesn't have 90 degree symmetry, so that's why we have a different looking figure after a quarter turn.
- b) The figure does have 180 degree symmetry. That's why it looks the same after a half turn (aka 180 degree turn)
- c) Rotating any figure 360 degrees, aka a full turn, will get everything back where it started. It doesn't matter if the figure has any symmetry or not.
