Classify Triangles by Angles

Front

What is an Acute Triangle?

Back

A triangle where all three angles are less than 90 degrees.

Front

What is a Right Triangle?

Back

A triangle that has one angle equal to 90 degrees.

Front

What is an Obtuse Triangle?

Back

A triangle where one angle is greater than 90 degrees.

Front

What is an Equiangular Triangle?

Back

A triangle where all three angles are equal, and each angle measures 60 degrees.

Front

How can you identify an Acute Triangle?

Back

If all angles are less than 90 degrees, it is an Acute Triangle.

Front

How can you identify a Right Triangle?

Back

If one angle is exactly 90 degrees, it is a Right Triangle.

Front

How can you identify an Obtuse Triangle?

Back

If one angle is greater than 90 degrees, it is an Obtuse Triangle.

Front

How can you identify an Equiangular Triangle?

Back

If all three angles are equal and each measures 60 degrees, it is an Equiangular Triangle.

Front

What is the sum of angles in any triangle?

Back

The sum of the angles in any triangle is always 180 degrees.

Front

Can a triangle have two obtuse angles?

Back

No, a triangle cannot have two obtuse angles because the sum would exceed 180 degrees.
