Front

What is the Law of Cosines?

Back

The Law of Cosines relates the lengths of the sides of a triangle to the cosine of one of its angles. It is used to find a side or angle in any triangle. Formula: c² = a² + b² - 2ab * cos(C).

Front

What is the longest side of a right triangle called?

Back

The longest side of a right triangle is called the Hypotenuse.

Front

What are Alternate Interior Angles?

Back

Alternate Interior Angles are pairs of angles that are on opposite sides of a transversal and inside the two lines. They are equal when the lines are parallel.

Front

What are Same Side Interior Angles?

Back

Same Side Interior Angles are pairs of angles that are on the same side of the transversal and inside the two lines. They are supplementary when the lines are parallel.

Front

What is the formula for finding the area of a triangle?

Back

Area = 1/2 * base * height.

Front

What is a right triangle?

Back

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

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). Formula: a² + b² = c².

Front

What is the difference between a scalene triangle and an isosceles triangle?

Back

A scalene triangle has all sides of different lengths, while an isosceles triangle has at least two sides of equal length.

Front

What is the sum of the interior angles of a triangle?

Back

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

Front

What is a transversal?

Back

A transversal is a line that intersects two or more lines at different points.
