scalene
isosceles
equilateral
equiangular
obtuse
right
acute

acute equilateral

Step-by-step explanation:

The triangle given fits both an equilateral (all equal sides) and acute triangle (all angles under 90°).  Here are the classifications explained:

scalene = all different side lengths

isosceles = two equal sides

equilateral = all equal sides

equiangular = all equal angles

obtuse = one angle greater than 90°

right = one angle exactly 90°

acute = all angles less than 90°

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
