What is the sum of the angles in a triangle?

Back

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

Front

Define parallel lines.

Back

Parallel lines are lines in a plane that never meet; they are always the same distance apart.

Front

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.

Front

What is the definition of a perpendicular line?

Back

Perpendicular lines are lines that intersect at a right angle (90 degrees).

Front

How do you find the measure of an arc in a circle?

Back

The measure of an arc can be found using the formula: Arc Measure = (Central Angle/360) * Circumference of the Circle.

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 area of a triangle?

Back

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

Front

Define complementary angles.

Back

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

Front

Define supplementary angles.

Back

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

Front

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

Back

The angles in a linear pair are supplementary, meaning they add up to 180 degrees.
