What is an exterior angle of a triangle?

Back

An exterior angle of a triangle is formed by one side of the triangle and the extension of an adjacent side. It is equal to the sum of the two opposite interior angles.

State 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). It can be expressed as: a² + b² = c².

How do you solve for x in the equation 7x + 35 = 63?

Back

To solve for x, subtract 35 from both sides to get 7x = 28, then divide both sides by 7 to find x = 4.

How do you calculate the distance between two points (x1, y1) and (x2, y2)?

Back

The distance (d) can be calculated using the distance formula: d = √((x2 - x1)² + (y2 - y1)²).
