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.

If ∠E ≅ ∠A, what does this mean?

Back

It means that angle E is congruent to angle A, indicating they have the same measure.

How do you find the value of x in a geometric problem?

Back

To find the value of x, set up an equation based on the relationships between the angles or sides given in the problem.

Front

What is the formula for the volume of a cylinder?

Back

The volume V of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

How do you calculate the volume of a sphere?

Back

The volume V of a sphere is calculated using the formula V = (4/3)πr³, where r is the radius.

Front

What is the relationship between complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What is the relationship between supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.

Front

How do you find the measure of an angle using the Triangle Sum Theorem?

Back

To find the measure of an angle, subtract the sum of the other two angles from 180 degrees.

Front

What is the formula for the area of a triangle?

Back

The area A of a triangle is given by the formula A = 1/2 * base * height.
