Labeling Figures in Geometry

This video tutorial covers the basics of labeling and naming geometric figures, including points, lines, line segments, rays, and planes. It explains how to identify and represent these figures using capital and lowercase letters, arrows, and other notations. The tutorial also discusses angles, triangles, and the concepts of collinearity and perpendicularity, providing examples and explanations to help students understand these geometric principles.

How do we label a point in geometry?

• With a number

• With a symbol

• With a lowercase letter

• With a capital letter

What is the correct way to represent a line?

• With a single point

• With two points and arrows on both ends

• With a single arrow

• With a dashed line

How do you label a line segment?

• With two endpoints and no arrows

• With two endpoints and arrows on both ends

• With a single point

• With a lowercase letter

What is the starting point of a ray called?

• Origin

• Endpoint

• Midpoint

• Vertex

How many non-collinear points are needed to define a plane?

• Five

• Three

• Two

• Four

How can a plane be named?

• Using a single lowercase letter

• Using a number

• Using a symbol

• Using a single italicized capital letter

What is the vertex of an angle?

• The point where the angle starts

• The point where the angle ends

• The point where the two rays meet

• The midpoint of the angle

How do you represent an angle with more than one angle at the same vertex?

• Using a number

• Using three letters

• Using a single letter

• Using a symbol

How do you label a triangle?

• Using a symbol

• Using a single point

• Using three points

• Using a number

What does it mean if points are collinear?

• They form a triangle

• They lie on the same line

• They form a right angle

• They are perpendicular
