Answer:
a scalene triangle has side lengths and angles that are all different.
a right triangle has one right angle (90 degree angle)
an equilateral triangle has all the same side lengths and angles
an isosceles triangle has 2 of the same side lengths and angles but not 3
Step-by-step explanation:
1: scalene triangle
2: right triangle
3: equilateral triangle
4: right triangle
5: scalene triangle
6: isosceles triangle
7: scalene triangle where x = 71 because a triangle's angles ALWAYS add up to 180. So 180-53-56 leaves us with the last angle which is 71
8: isosceles triangle where x = 65 did 180-50-65
9: right triangle where x =45 you can tell that one angle is perfectly 90 degrees so 180-45-90 is 45
10: equilateral triangle... all three sides have 1 dash, meaning they are all the same length and x=60 because equilateral triangles have 3 equal angles that add up to 180 so 180/3 is 60
