Match the side and angle measures of each triangle to its correct classification angle measures: 26, 36, 118.
side lengths: 1.5in.. , 2in, 3in.

angle measures: 60, 60, 60,
side lengths: 4in, 4in, 4in,

angle measures: 22, 68, 90,
side lengths: 5in, 12in, 13in,

angle measures: 38, 38, 104,
side lengths: 8in, 8in, 11in,

acute equilateral
obtuse isosceles
right scalene
obtuse scalene
which one is it??

unless you made a typo, the answers are both a and c.

step-by-step explanation:

1.5/3 is .5 whereas 3/9 is .3333333 not proportional

22/33 is .66666 and 4/6 is also .66666 proportional

2/4 is .5 whereas 142/213 is .66666 not proportional

14/7 is 2 and 7/3.5 is also 2 proportional

you could've also checked it by doing this simple division:

if the larger fraction divides with the smaller fraction to equal 1, it is proportional. so let me show you what i mean:

when i divide 22/33 by 4/6 i get 1, so we know it is proportional, and it is the same with 14/7 and 7/3.5. now if i divide 3/9 by 1.5/3 i get .66666 so therefore we know it is not proportional.

there are many ways to do this so i wanted to show you some possible ways.
