 Perpendicular Lines – 2 lines that intersect to form right angles  Alternate Exterior Angles – angles that lie on opposite sides of the transversal on the outside of the parallel lines.  Equilateral Triangle – a triangle with 3 congruent sides Vocabulary

 Forms a right angle Perpendicular Lines

 The alternate exterior angles in this picture would be <1 and <8  Also <2 and <7  Because they lie on the opposite sides of the transversal or line that intersects 2 or more lines Alternate Exterior Angles

 All sides of a equilateral triangle are congruent or equal Equilateral Triangle

Perpendicular Lines & Alternate Exterior Angles

Alternate Exterior Angles

How do you know when you have perpendicular lines? Practice

Give 2 examples of Alternate Exterior Angles. Alternate Exterior Angles

Give reasons why this is an equilateral triangles. Equilateral Triangles
