Classify Triangles by Angle

Front

What is an acute triangle?

Back

An acute triangle is a triangle where all three angles are less than 90 degrees.

Front

What is an obtuse triangle?

Back

An obtuse triangle is a triangle that has one angle greater than 90 degrees.

Front

What is a right triangle?

Back

A right triangle is a triangle that has one angle equal to 90 degrees.

Front

How can you classify a triangle based on its angles?

Back

Triangles can be classified as acute, obtuse, or right based on the measures of their angles.

Front

What is the sum of the angles in any triangle?

Back

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

Front

If one angle of a triangle is 95 degrees, what type of triangle is it?

Back

It is an obtuse triangle because it has one angle greater than 90 degrees.

Front

Can a triangle have two obtuse angles?

Back

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

Front

What is the relationship between acute triangles and their angles?

Back

In an acute triangle, all angles are less than 90 degrees, making it a triangle with sharp angles.

Front

What is the relationship between obtuse triangles and their angles?

Back

In an obtuse triangle, one angle is greater than 90 degrees, making it a triangle with a 'wide' angle.

Front

How do you determine if a triangle is acute, obtuse, or right?

Back

Measure the angles of the triangle: if all are less than 90 degrees, it's acute; if one is greater than 90 degrees, it's obtuse; if one is exactly 90 degrees, it's right.
