Answer:
1. MI = MS why?
-because MI and MS are the sides of the triangle MIS and an equiangular triangle has three equal sides, and it is the same as an equilateral triangle so that's why MI is congruent to MS.
2. What kind of triangle is MIS?
-triangle MIS is a equilateral and equiangular triangle.
3. What angles are congruent? why?
-all of the angles are congruent. Why? because in an equiangular triangle, the measure of each of its interior angles is 60 ̊it means that all angles measures 60° , so they are congruent.
4. MI = IS Why?
-because MI and IS are also the sides of the triangle MIS which is an equiangular triangle that has three equal sides.
