A triangle has side lengths of 5, 12, and 13 inches. The angle measures are 90°, 23°, and 67°. What is the best name for the triangle? acute, isosceles
right, scalene
obtuse, equilateral
acute, equilateral

Not sure but I would say scalene
because if you think about it like all of the measurements are different so it’s not equilateral or right probably not isosceles

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
