Ineed this is so hard i need to pass geometry me

A. Acute
and
B. Isosceles
and
D. Equilateral
This is because the triangle has all 3 sides and angles marked congruent, making it equilateral. This also automatically means that the triangle is also acute, because all equilateral triangles are acute (every angle is less than 90 degrees). 
it is also isosceles because every equilateral triangle is isosceles. 
It is also not a right triangle because no right angles are marked.
It is not obtuse because all the angles are equiangular, so they can't be obtuse (they're acute). 
And is is not scalene because sides are marked congruent, and in a scalene triangle no sides are congruent. 

Acute
Isosceles (at least 2 sides are congruent)
and equalateral

Ibelieve your answer would be 8.

Idon’t know this and this isn’t middle school work
