Flashcard - Triangle Angle Sum

Front

What is the Triangle Angle Sum Theorem?

Back

The Triangle Angle Sum Theorem states that the sum of the interior angles of a triangle is always 180 degrees.

Front

If two angles of a triangle are 50 degrees and 60 degrees, what is the measure of the third angle?

Back

The third angle is 70 degrees, calculated as 180 - (50 + 60).

Front

What is the measure of each angle in an equilateral triangle?

Back

Each angle in an equilateral triangle measures 60 degrees.

Front

How do you find a missing angle in a triangle?

Back

To find a missing angle, subtract the sum of the known angles from 180 degrees.

Front

What is the maximum angle measure in a triangle?

Back

The maximum angle measure in a triangle is less than 180 degrees.

Front

Can a triangle have two right angles?

Back

No, a triangle cannot have two right angles because the sum of angles would exceed 180 degrees.

Front

What is an obtuse triangle?

Back

An obtuse triangle is a triangle that has one angle measuring more 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

If one angle of a triangle is 90 degrees, what type of triangle is it?

Back

It is a right triangle.

Front

What is the relationship between the angles in a triangle and its exterior angle?

Back

The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
