1. Equilateral Triangle
2. Isosceles Triangle
3. Scalene Triangle
4. Right Triangle
5. Obtuse Triangle
6. Acute Triangle
7 . Obtuse Triangle because
one angle is greater than 90
degrees.
8 Isosceles Triangle because
it has two angles that are
congruent. Is also an Acute
Triangle because all angles
measure less than 90. Either
answer is correct.
9. Equilateral Triangle
because all angles and sides
are congruent. Is also an
Acute Triangle because all
angles measure less than 90
degrees. Either is correct.
10. Right Triangle. Also is
an Isosceles Triangle since it
has two congruent angles.
Either answer is correct.
11. No. Every triangle has
two acute angles. A right
angle is 90 degrees, so it is
impossible to have an obtuse
angle in a right triangle.
12. Scalene Triangle
13 The triangle is obtuse.
14 The triangle is right.
15. The triangle is scalene
16. x=40°
17. a=35°
18. The triangle is isosceles.
40°+68°+72°= 180°
35°+55°+90° = 180°
