2. If the point is reflected across the x axis, the x position will stay the same. The y position Will have it's sign flipped. Vice Versa if the point is reflected across the y axis.
3. Just mentally move the point. X coord marks the left/right and Y coord marks up/down.
The answer would be 65°. This is because 180° -50° equals 130°. And 130° divided by two equals 65°. The two remaining angles must be equal because it is an isosceles triangle.
