Chapter 5 - Geometry and Measures Flashcards
1
Q
what are the five rules of geometry
A
triangles = 180 straight line = 180 quadrilateral = 360 angles on a point = 360 isosceles = 2 sides and angles the same
2
Q
what are the parallel line rules
A
alternate angles = same
allied = add to 180
corresponding = add to 180
3
Q
how do you find the sum of interior angles
A
(n-2) x 180
4
Q

A
Translations
Rotations
reflections
Enlargements
6
Q
