What is the formula for the area of a circle?

Back

The area of a circle is given by the formula: A = πr², where r is the radius of the circle.

What does 'Soh Cah Toa' represent in trigonometry?

Back

Soh Cah Toa is a mnemonic to remember the definitions of sine, cosine, and tangent: Soh = Sine = Opposite/Hypotenuse, Cah = Cosine = Adjacent/Hypotenuse, Toa = Tangent = Opposite/Adjacent.

What is the Division Property of Equality?

Back

The Division Property of Equality states that if you divide both sides of an equation by the same non-zero number, the two sides remain equal.

How do you find the measure of an angle when given another angle in a triangle?

Back

In a triangle, the sum of the interior angles is always 180°. If you know one angle, you can find the others by subtracting the known angle from 180°.

Front

What is the formula to find the sum of the interior angles of a polygon?

Back

The sum of the interior angles of a polygon can be calculated using the formula: (n - 2) × 180°, where n is the number of sides in the polygon.

Front

What is the area of a circle with a radius of 3 cm?

Back

Using the formula A = πr², the area is A = π(3)² = 28.26 cm².

Front

What is the relationship between the angles in a linear pair?

Back

Angles in a linear pair are supplementary, meaning they add up to 180°.

Front

What is the Pythagorean theorem?

Back

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b): a² + b² = c².

Front

What is the formula for the circumference of a circle?

Back

The circumference of a circle is given by the formula: C = 2πr, where r is the radius.

Front

What is the definition of complementary angles?

Back

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