Ordering Triangle Sides & Angles

Front

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

Back

In a triangle, the larger the angle, the longer the opposite side. Conversely, the smaller the angle, the shorter the opposite 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

What is the smallest angle in a triangle?

Back

The smallest angle in a triangle is the one opposite the shortest side.

Front

How do you find the measure of an angle in a triangle?

Back

You can find the measure of an angle using the triangle sum theorem, which states that the sum of the angles in a triangle is always 180 degrees.

Front

What is the triangle inequality theorem?

Back

The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Front

How do you order sides of a triangle from least to greatest?

Back

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

Front

What is the measure of the angles in a right triangle?

Back

In a right triangle, one angle measures 90 degrees, and the sum of the other two angles is 90 degrees.

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 scalene triangle?

Back

A scalene triangle is a triangle where all three sides have different lengths.
