Ordering Sides and Angles of a Triangle

Front

What is the relationship between the angles and sides of a triangle?

Back

In a triangle, the largest angle is opposite the longest side, and the smallest angle is opposite the shortest side.

Front

How do you order angles in a triangle from smallest to largest?

Back

To order angles from smallest to largest, compare their measures. The angle with the smallest measure comes first.

Front

How do you order sides in a triangle from longest to shortest?

Back

To order sides from longest to shortest, compare their lengths. The side with the longest length comes first.

Front

What is the sum of the angles in a triangle?

Back

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

Front

If angle A is 30 degrees and angle B is 60 degrees, what is angle C?

Back

Angle C is 90 degrees, since 30 + 60 + C = 180.

Front

What is the definition of an acute triangle?

Back

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

Front

What is the definition of an obtuse triangle?

Back

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

Front

What is the definition of a right triangle?

Back

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

Front

How can you determine the longest side of a triangle?

Back

The longest side can be determined by identifying the angle with the largest measure, as it is opposite the longest side.

Front

What is the relationship between the sides of a triangle and the angles?

Back

The side lengths of a triangle are directly related to the angles; larger angles correspond to longer sides.
