By angle:
We can classify a triangle 4 different ways when we're judging it by it's angle(s).
Acute: A triangle where all angles are less than 90 degrees.
Obtuse: A triangle where one angle is greater than 90 degrees.
Right: A triangle where one of the angles is exactly 90 degrees.
Equiangular: A triangle where all angles are the same (60 degrees.)
We can also classify a triangle by its sides:
Equilateral: (technically the same as an equiangular triangle, in order to have 3 equal sides you must have 3 equal angles as well.)
Isosceles: Two sides are the same length, where one is not.
Scalene: All three sides are different lengths.
I hope this helps!
Answer:
Below in bold.
Step-by-step explanation:
f(x) = 1/2x^2 + 4x
Convert to vertex form:
f(x) = 1/2(x^2 + 8x)
= 1/2 [(x + 4)^2 - 16]
= 1/2(x + 4)^2 - 8 <------ Vertex form.
So the Vertex is at (-4, - 8).
Axis of symmetry is x = -4.
y -intercept (when x = 0) = 8-8 = 0.
