Outcomes E1-E5 INTRODUCTION TO TRANSFORMATIONS

Coming into the Triangles Unit, we need to remember certain vocabulary. In the following game, teams will be matching up definitions with the word list. The words we are trying to define are: opposite angles, complementary angles, supplementary angles, translation, rotation, reflection, dilatation, scale, proportion, unique triangle, similar triangle, congruent triangle, equilateral triangle, scalene triangle and isosceles triangle REMEMBER THOSE WORDS…?

Property of shapes. A flip is known as a ___________________ DEFINITION 1

Property of shapes. A turn is known as a ___________________ DEFINITION 2

Triangles where all the sides are the same length are ____________ DEFINITION 3

Property of triangles. Triangles that have different shapes and different sizes are known as_______________ DEFINITION 4

Property of triangles. Triangles that have the same shape and same sizes are known as_______________ DEFINITION 5

Property of shapes. An enlargement is known as a ___________________ DEFINITION 6

Property of triangles. Triangles that have the same shape but in different sizes are known as_______________ DEFINITION 7

___________________ is when 2 ratios are considered to be the same. DEFINITION 8

Triangles where none of the sides are the same are -________________ DEFINITION 9

Triangles where 2 of the sides are the same are -________________ DEFINITION 10

A flip, turn, slide or resizing of a pre-image to make an image is called a ________________ DEFINITION 11

Each person will be given a piece of paper with instructions on it (DO NOT LOOK AT IT) We will all be moving in a space, and #1-5 will open their papers, after that #6-10, the #11-15 and so on Follow the instructions on your paper Keep you instructions secret! NEW GAME! TRIANGLE DRAMA
