Measuring & Constructing Angles - GEOMETRY 1.3

The video tutorial covers the basics of angles in geometry, including their components such as rays and vertices. It explains how angles are measured in degrees and describes different types of angles like acute, right, obtuse, and straight angles. The tutorial also introduces the concepts of congruent and bisected angles, and provides guidance on labeling angles and solving related problems.

What is the point called where two rays meet to form an angle?

• Vertex

• Nadir

• Summit

• Apex

How many degrees is a right angle?

• 360 degrees

• 45 degrees

• 90 degrees

• 180 degrees

Which type of angle is greater than 90 degrees but less than 180 degrees?

• Acute angle

• Straight angle

• Obtuse angle

• Right angle

What does it mean if two angles are congruent?

• They are complementary

• They are equal in measure

• They are supplementary

• They are adjacent

What is the result when an angle is bisected?

• The angle is halved

• The angle is tripled

• The angle is doubled

• The angle remains the same

When labeling an angle, which point must be the vertex?

• Any point

• The first point

• The second point

• The third point

If angle JKL is 42 degrees and angle LKM is 28 degrees, what is the measure of angle JKM?

• 70 degrees

• 90 degrees

• 80 degrees

• 60 degrees
