an equilateral triangle has all its angle and sides equal
Each angle has a measure of 120 degrees
Not necessarily. The two equal angles in an isosceles triangle must both be acute angles. If they were right angles or obtuse angles then a triangle could not be formed. If the two equal angles are less than 45° each then the third angle is an obtuse angle. If they are both 45° then the third angle is a right angle and if they are both greater than 45° then the third angle is an acute angle.
It is to bisect the angle into two equal angles.

There is no figure to be seen but an isosceles trapezoid will have equal base angles.

The property that states the interior angles of any three sided figure can be demonstrated in the following geometric formula. In any three sided figure; angle "A" + angle "B" + angle "C" = 180 degrees
Well for a four sided figure the sum of the angles must equal 360 degrees
Obtuse triangles have an obtuse angle, and regular shapes with a number of sides equal to or greater than five have angles that are all obtuse.
An angle with equal sides but not angles.
If two angles are equal, they're called congruent angles.
