3.1 identify paris of lines and angles

Mr. Saucedo

Geometry

We will identify angle pairs formed by three intersecting lines.

DEFINITIONCoplanar lines that do not intersect

VISUAL

LABELWe use two vertical parallel lines to indicate

parallelism.

DEFINITIONFormed when two lines make at least one

90 degree angle.

VISUAL

DEFINITIONTwo lines that do not intersect and are NOT

coplanar.

VISUAL

DEFINITIONTwo planes that do not intersect.

VISUAL

DEFINITIONA line that intersects two or more coplanar

lines at different points.

VISUAL

Look at the figure and respondThe following questions.

A. Name two parallel lines.B. Name two skew lines.C. Name two parallel planes.D. Is there a transversal line in this figure?

DEFINITIONAngles that have a corresponding (similar)

position.

VISUAL

DEFINITIONTwo angles that lie between two lines and

on opposite sides of the transversal.

VISUAL

DEFINITIONTwo angles that lie outside two lines and

opposite sides of a transversal.

VISUAL

DEFINITIONTwo angles that lie between two lines and

on same side of transversal.

VISUAL

Look at the following sketch and answer the following questions.

A. Name two corresponding angles.B. Name two alternate interior angles.C. Name two alternate exterior angles.D. Name two consecutive interior angles.E. <2 and <8 are ___________________.F. <7 and <8 are ___________________.G. <3 and <5 are ___________________.

Draw this on the RIGHT side of your notes, in your notebook, for today.
