Ch 1: Geometry Basics Review

What is the definition of an angle?

• An angle is formed by two rays that share a common endpoint, called the vertex.

• An angle is a measure of the distance between two points.

• An angle is a straight line that connects two points.

• An angle is a figure formed by three intersecting lines.

What is the difference between acute, obtuse, and reflex angles?

• An acute angle is greater than 90 degrees, an obtuse angle is less than 90 degrees, and a reflex angle is equal to 180 degrees.

• An acute angle is less than 90 degrees, an obtuse angle is greater than 90 degrees but less than 180 degrees, and a reflex angle is greater than 180 degrees.

• An acute angle is equal to 90 degrees, an obtuse angle is greater than 180 degrees, and a reflex angle is less than 90 degrees.

• An acute angle is less than 45 degrees, an obtuse angle is greater than 45 degrees but less than 90 degrees, and a reflex angle is equal to 360 degrees.

What is the definition of parallel lines?

• Lines that intersect at a right angle.

• Lines that meet at a point.

• Lines in a plane that never meet; they are always the same distance apart.

• Lines that curve away from each other.

How do you find the missing angle in a triangle?

• By measuring the angles directly

• By using the Pythagorean theorem

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

• 180 degrees

• 360 degrees

• 270 degrees

• 90 degrees

What is the formula for the area of a triangle?

• Area = base × height

• Area = \frac{1}{2} \times base \times height

• Area = base + height

• Area = \frac{1}{3} \times base \times height
