Triangle Sum Theorem Assignment

Front

What is the Triangle Sum Theorem?

Back

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

Front

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

Back

It is a right triangle.

Front

Solve for x: If angle A = 50 degrees and angle B = 60 degrees, what is angle C?

Back

Angle C = 70 degrees (since 50 + 60 + C = 180).

Front

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

Back

Each angle in an equilateral triangle measures 60 degrees.

Front

If two angles of a triangle are 45 degrees and 45 degrees, what is the measure of the third angle?

Back

The third angle measures 90 degrees.

Front

What is the relationship between the angles in a triangle?

Back

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

Front

If angle A = 30 degrees and angle B = 70 degrees, what is angle C?

Back

Angle C = 80 degrees (since 30 + 70 + C = 180).

Front

What is the formula to find the missing angle in a triangle?

Back

The formula is: Missing angle = 180 - (sum of the other two angles).

Front

If angle A = 120 degrees, what can you say about triangle ABC?

Back

Triangle ABC is an obtuse triangle because it has one angle greater than 90 degrees.

Front

What type of triangle has all angles less than 90 degrees?

Back

It is called an acute triangle.
