Ordering Triangle Sides & Angles

Front

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

Back

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

Front

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

Back

To order the sides, compare their lengths. The side with the smallest length comes first, followed by the next smallest, and so on.

Front

What is the largest angle in a triangle?

Back

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

Front

How do you determine the smallest angle in a triangle?

Back

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

Front

If two sides of a triangle are equal, what can you say about the angles opposite those sides?

Back

The angles opposite the equal sides are also equal.

Front

What is the sum of the angles in any triangle?

Back

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

Front

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

Back

You can find the measure of an unknown angle by subtracting the sum of the known angles from 180 degrees.

Front

What is the relationship between the sides and angles in a right triangle?

Back

In a right triangle, the side opposite the right angle is the longest side (hypotenuse), and the other two sides are shorter.

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 list angles in order from largest to smallest?

Back

To list angles from largest to smallest, compare their measures and arrange them accordingly.
