Step-by-step explanation:

If no sides of a triangle are congruent (equal) then it is SCALENE

If two sides of a triangle are congruent (equal) then it is ISCOSCELES

If all sides of a triangle are congruent (equal) then it is EQUILATERAL

90, 35, 55: no sides are congruent = SCALENE

700, 550, 550: two sides are congruent = ISCOSCELES

350, 400, 1000: no sides are congruent = SCALENE

460, 460, 440: two sides are congruent = ISCOSCELES

1200, 300, 300: two sides are congruent = ISCOSCELES
