Question

Classify the following triangle as acute, obtuse, or right.

Answer 1

Obtuse

Explanation:

The size of the triangle should tell you that. There is no 90 degree angle on it so it is not a right triangle. It is not smaller than a right triangle so it cannot be an acute triangle. It is bigger than a right triangle so it is an obtuse triangle.

Answer 2

Obtuse

Explanation:

an Acute triangle is a triangle that all 3 angles are less than 90*

a Right triangle is a triangle that has one right angle, or an angle that is exactly 90*

an Obtuse triangle is a triangle that has at least one obtuse angle, or an angle that is greater than 90*

This triangle's angles are 132*, 36*, and 12*

Because 132* is greater than 90*, that makes the angle obtuse. Because the triangle has one obtuse angle, that makes the triangle an obtuse triangle

Hope this helps : )
