Front

What is the largest angle in a triangle related to?

Back

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

Front

Can a triangle be formed with side lengths: 10, 12, 22?

Back

No, a triangle cannot be formed with these side lengths because the sum of the lengths of the two shorter sides (10 + 12 = 22) is not greater than the length of the longest side (22).

Front

Can a triangle be formed with side lengths: 4, 7, 10?

Back

Yes, a triangle can be formed with these side lengths because the sum of the lengths of the two shorter sides (4 + 7 = 11) is greater than the length of the longest side (10).

Front

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

Back

To order the sides of a triangle from greatest to least, compare the lengths of each side and arrange them accordingly.

Front

Where is the largest angle of a triangle located?

Back

The largest angle of a triangle is located across from the longest side.

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

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

Back

In a triangle, the larger the angle, the longer the side opposite that angle.

Front

What is an obtuse triangle?

Back

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

Front

What is an acute triangle?

Back

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

Front

What is a right triangle?

Back

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