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 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 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

How do you determine the longest side of a triangle?

Back

The longest side of a triangle is opposite the largest angle.

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

Back

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

Front

If side AB is 5 cm, side AC is 7 cm, and side BC is 10 cm, order the sides from shortest to longest.

Back

The order is AB, AC, BC.
