Ordering Triangle Sides & Angles

Front

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

Back

The longest side of a triangle is always opposite the largest angle, and the shortest side is opposite the smallest angle.

Front

How do you determine the order of angles in a triangle?

Back

To order angles from least to greatest, compare their measures. The angle with the smallest measure is the least, and the angle with the largest measure is the greatest.

Front

What is the smallest angle in a triangle?

Back

The smallest angle is the one opposite the shortest side.

Front

How do you find the longest side of a triangle?

Back

The longest side is located across from the largest angle.

Front

If angle A is 30 degrees, angle B is 60 degrees, and angle C is 90 degrees, order the angles from least to greatest.

Back

A, B, C

Front

In triangle ABC, if AB = 5, AC = 7, and BC = 10, order the sides from least to greatest.

Back

AB, AC, BC

Front

What is the sum of the angles in a triangle?

Back

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

Front

If two angles in a triangle are equal, what can be said about the sides opposite those angles?

Back

The sides opposite the equal angles are also equal in length.

Front

What is the definition of an obtuse triangle?

Back

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