Question

The angle measures in a triangle are 25 degrees, 135 degrees, and 20 degrees. what type of triangle is it. isosceles triangleobtuse triangle right triangle acute triangle

Answer 1

25 degrees, 135 degrees, and 20 degrees

no 90 degree angle, so not a right triangle

all three angles are different, so not an isosceles triangle

135 > 90, so not an acute triangle

must be an obtuse triangle
