Answer:
The sum of the interior angles of a triangle is 180 degrees.
d. Scalene
e. Isosceles
f. Isosceles
g. Equilateral
h. Scalene
i. Equilateral
j. Right
l. Acute
m. Obtuse - doesn't add to 180 not a triangle
n. Acute - doesn't add to 180 not a triangle
o. Obtuse
Step-by-step explanation:
The interior angles of a triangle add to 180 degrees. There are two ways we classify triangle by side lengths and angle measures.
Side lengths: Compare the side lengths and see if any are equal to determine the type.
- Scalene: 3 different lengths
- Isosceles: 2 equal lengths and 1 different
- Equilateral : 3 equal sides
Angle Measures: Compare the angles measures to 90 degrees.
- Right: If one angle is equal to 90
- Acute: All angles are less than 90 degrees
- Obtuse: One angle is greater than 90 degrees
A, 2.
Step-by-step explanation:
The formula is (y2-y1)/(x2-x1) so just follow that.
I'm pretty sure the answer is 12.
