Question

Classify the triangle by its angles.

Answer 1

35+118+27=180 so this is a triangle

Answer 2

Step-by-step In an acute triangle all three angles are acute (less than 90 degrees). A right triangle contains one right angle and two acute angles. And an obtuse triangle contains one obtuse angle (greater than 90 degrees) and two acute angles. And an isosceles triangle has two congruent angles.
