measuring angles

What is the sum of angles in a triangle?

• 90 degrees

• 180 degrees

• 360 degrees

• 270 degrees

What is an angle?

• An angle is formed by two rays (sides of the angle) that share a common endpoint (the vertex).

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

• An angle is a type of polygon with three sides.

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

What is the formula for finding the measure of an exterior angle of a triangle?

• The measure of an exterior angle is equal to the sum of the measures of the two non-adjacent interior angles.

• The measure of an exterior angle is equal to the difference of the measures of the two adjacent interior angles.

• The measure of an exterior angle is equal to the sum of all three interior angles.

• The measure of an exterior angle is equal to half the measure of the opposite interior angle.

What is a full rotation in degrees?

• 180 degrees

• 360 degrees

• 90 degrees

• 270 degrees

What is the difference between a vertical angle and an adjacent angle?

• Vertical angles are equal and formed by two intersecting lines, while adjacent angles share a common side and vertex but do not overlap.

• Vertical angles are always acute, while adjacent angles are always obtuse.

• Vertical angles are formed by parallel lines, while adjacent angles are formed by perpendicular lines.

• Vertical angles are angles that are next to each other, while adjacent angles are opposite angles.

How can angles be classified based on their measures?

• Acute, right, obtuse, straight, reflex, or full rotation

• Only acute and obtuse

• Right and straight only

• Acute and reflex only

What is the relationship between complementary angles?

• They are two angles that add up to 90 degrees.

• They are two angles that add up to 180 degrees.

• They are two angles that are equal in measure.

• They are two angles that are adjacent to each other.

What is a reflex angle?

• An angle that measures exactly 180 degrees.

• An angle that measures less than 90 degrees.

• An angle that measures more than 180 degrees but less than 360 degrees.

• An angle that measures exactly 360 degrees.

What is the unit of measurement for angles?

• Degrees (°)

• Meters (m)

• Liters (L)

• Seconds (s)

How do you measure an angle using a protractor?

• Align the protractor's baseline with one side of the angle and read the measurement where the other side intersects the protractor's scale.

• Place the protractor on the table and measure the angle from the edge of the table.

• Use a ruler to measure the length of the angle's sides and calculate the angle using trigonometry.

• Draw a straight line and measure the angle using a compass.
