HW 4.2

Front

What is the measure of angle b if it is given as 36 degrees?

Back

Angle b measures 36°.

Front

How do you find the indicated angle measure in a geometric figure?

Back

To find the indicated angle measure, use the properties of angles, such as the sum of angles in a triangle or the relationships between interior and exterior angles.

Front

What is the measure of the indicated angle if it is stated as 36?

Back

The indicated angle measures 36°.

Front

What are remote interior angles in relation to an exterior angle?

Back

Remote interior angles are the two angles inside a triangle that are not adjacent to the exterior angle.

Front

Which angles are considered remote interior angles to Angle W?

Back

Angle X and Angle Y are the remote interior angles to Angle W.

Front

What is an exterior angle in a triangle?

Back

An exterior angle is formed by one side of a triangle and the extension of an adjacent side.

Front

What is the relationship between an exterior angle and the remote interior angles?

Back

The measure of an exterior angle is equal to the sum of the measures of its remote interior angles.

Front

How do you calculate the measure of an angle in a triangle?

Back

The sum of the interior angles in a triangle is always 180°. Use this property to calculate the measure of an unknown angle.

Front

What is the definition of an angle?

Back

An angle is formed by two rays with a common endpoint, called the vertex.

Front

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

Back

An acute angle measures less than 90°, a right angle measures exactly 90°, and an obtuse angle measures more than 90° but less than 180°.
