Given the angles of a triangle learn how to classify the triangle ex 3

The video tutorial explains how to classify triangles based on their angles. It covers equilateral triangles, where all angles are equal and acute; right triangles, which include a right angle; obtuse triangles, which have one angle greater than 90 degrees; and acute triangles, where all angles are acute. The tutorial concludes that the given triangle is acute.

• It has one obtuse angle.

Which of the following is true about a right triangle?

• It has all angles equal.

• It has one angle greater than 90 degrees.

• It has one angle equal to 90 degrees.

• It has all angles less than 90 degrees.

What is a defining feature of an obtuse triangle?

• All angles are less than 90 degrees.

• All angles are equal.

• It has one angle equal to 90 degrees.

• It has one angle greater than 90 degrees.

Which statement is true about an acute triangle?

• All angles are less than 90 degrees.

• All angles are greater than 90 degrees.

• It has one angle greater than 90 degrees.

• It has one angle equal to 90 degrees.
