converse of the angle bisector theorem
answers
It is impossible to tell since there is no accompanying figure!
Reflection symmetry.
IIt is not possible to list all the properties since more can be derived from the ones give. The basic one is that all three sides are of equal length. From this, it can be shown that all angles must also be equal, and so = 60 deg. Then you can show that the medians, altitudes, perpendicular bisectors of sides and angle bisectors are coincident. That means the centroid, circumcentre, incentre are the same. It has rotational symmetry of order 3 It has 3 axes of symmetry.
Two angles are said to be complementary angles if their sum is 90 degrees. The angles A and B shown in the figure are complementary since their angle sum is 90°. + B = 90° B Two angles are said to be supplementary angles if their sum is 180 degrees. The angles A and B shown in the figure are complementary since their angle sum is 180°.
